Drop the Pen! What Every Writer Should Know About Real Police Work: You Have the Right to Learn About the Miranda Warning

Writers, stop winging police dialogue. If your cop character is cuffing suspects, they’d better know when (and how) to use the Miranda Warning. Here’s what every writer needs to get right about real-world police procedure—and why it matters.


“You have the right to remain silent. Anything you say can be used against you in a court of law…or in a good tabloid story.” Leslie Nielsen in the 1988 police comedy, The Naked Gun.

Once upon a time there was a fellow by the name of Ernesto Miranda who did not play well with others. He spent the bulk of his life in jails and prison, and that revolving cell door pattern would continue for the rest of his life until he died from stab wounds incurred during a 1976 bar fight. His life was one of rage and pain and waste. 

But he changed criminal investigations forever. 

In 1963 Miranda kidnapped and sexually assaulted an eighteen-year-old woman in Phoenix, Arizona. The woman Miranda attacked was able to provide a solid description, as well as the make, model, color, and partial license plate of his pickup. Phoenix P.D. officers picked him up, whereupon detectives put him in a lineup and interrogated him until he confessed. Miranda was found guilty at trial, which is when the story takes a turn. 

The case was appealed all the way to the Supreme Court, where the conviction was thrown out stemming from the fact the detectives had not adequately ensured Mr. Miranda understood his Fifth Amendment right to be silent while being questioned as a criminal suspect, as well as his Sixth Amendment right to have an attorney present during interrogation by the police. 

To be clear, the Phoenix officers did some solid police work, but the times, they were a-changin’, and so was legal precedent. Few police professionals had thought about reminding suspects they had constitutional rights, and the very idea of giving people accused of violent crimes such a reminder would have been about as popular as a cop walking into a squad room wearing a duty belt under a tutu.

The Miranda vs. Arizona ruling changed everything when it came to police interrogations. Nowadays, as I’m sure you’ve surmised from police procedurals in films and novels, officers dutifully issue the warning at the point of arrest as a matter of routine and departmental policy. 

I wonder how many times we’ve heard fictional cops recite the Miranda warning on television. I bet you could list the whole thing from memory the next time you make a citizen’s arrest.  I should point out a couple of things before we continue: 

  1. It’s best to not have your cop character recite Miranda from memory. I’ll tell you why in a minute.

  2. Most of the time, it’s best to avoid making a citizen’s arrest in real life. It’s dangerous, it can get you sued, and you’ll end up on someone’s social media feed looking like a big old citizens’-arrest-making doofus. 

It's conceivable you’re writing about a police detective or patrol officer who will wind up reading the warning. You have some wiggle room depending on how detailed you want to be with the project, so let’s examine a few ways Miranda can or should be applied so that you can make informed decisions as you delve deeper into your work in progress. 

The Miranda Warning must be read to a criminal suspect if that person is not allowed to leave and the questions to be posed by the police investigators could be used against the suspect at trial. Both elements must be in place for the warning to be required. So, your protagonist might make an arrest but have no plans to ask follow-up questions. In this case, your fictional cop might not give the Miranda Warning at all. 

An example is the arrest of a man for an outstanding warrant for failure to pay child support. The warrant was discovered when a patrol officer pulled him over for speeding through a school zone, and a check of the driver’s license through the National Crime Information Center (NCIC) resulted in a warrant “hit.” The officer in this scenario has no involvement in the child support case, so there is no reason to ask questions about it. Thus, the officer would most likely serve the warrant but not ask the suspect anything about it. 

An investigator may also opt against giving the warning if she wants to ask potentially incriminating questions but has no plans to make an immediate arrest. In this instance, she could ask questions as long as she lets the suspect leave when questioning is done. This is a legally sound strategy, albeit a risky one. Conceivably, the suspect could confess to the beheading of his ex-wife, and the detective would still have to let him go. That’s not to say she couldn’t go get an arrest warrant and pick him up later, but an axe murderer is walking the streets in the meantime. 

I used this technique twice in my career. In one of those instances, I was out on a case and working alone. I suspected a young man of participating in a gang-related shooting the day before. I’d learned from an informant that the man had helped the shooting suspect by picking up the spent bullet casings at the crime scene. He was in hot water for tampering with evidence, but he was also a witness to the actual shooting. I needed him to cooperate, and I had to make some quick decisions to make that happen. 

The young man was stronger and faster than me. Arresting him alone could have gotten someone hurt (probably me, if we’re being honest), and it also would have shut down any chance of getting him to talk to me. Asking him questions about the part he played in the aftermath of the shooting would incriminate him, but I was certain giving him his rights in that moment would have spooked him. Thus, I asked about the shooting and suggested (honestly) that his cooperation could help him if and when he was arrested for the evidence tampering charge. 

Using this tactic requires officers to be fully transparent about their intentions. Suspects can’t read minds, and many believe they are not free to go at any time. It is incumbent upon the officer to make it clear throughout the interview that the person being questioned is not in custody. Thus, an investigating officer would literally say, “Listen, you’re free to go, but I’d appreciate a few minutes of your time.” 

This also means the officer’s body language must match what she said. She can’t stand between the person being questioned and the exit door so there is no confusion about how and where the person can leave. Your fictional detective will likely keep the conversational tone light, and it is always best practice to record the conversation, so judges and juries know she was upfront with her intentions and upheld her commitment. 

I mentioned earlier that it is a good idea for cops to refrain from giving the warning from memory. It looks slick on film, but it can be awkward in real life if you stumble over the wording or leave out one of the required elements entirely. This can happen when adrenaline is up, so every detective I’ve ever known carried a laminated copy of the warning in their badge wallet. 

This can also be a crucial element at trial. A defense attorney might ask the testifying officer if he gave the warning from memory. An inexperienced officer might answer, “I did it from memory,” with a smug look on his face, thinking this is some sort of IQ test he just passed. 

Unfortunately, his day just got a little longer, because the next question out of the attorney’s mouth will be, “Would you please recite that for us now…from memory.” 

I don’t care how tough you are or how comfortable you feel talking in front of a judge, jury, the accused, the lawyers for the accused, and an audience watching the trial. You are going to mess up when called upon to recite under such duress, at which point the attorney will make hay out of the suspicion you didn’t correctly provide the suspect his rights. 

Conversely, if you testify you read the Miranda Warning off a laminated card, the attorney is likely to drop the entire line of questioning. It’s safer and more professional, and it is simply a better way to get the job done. 

I have one more thought on the Miranda Warning. Yes, it can be a bit of a hassle, and it might be the catalyst for the suspect to clam up and ask for a lawyer. It is also true that hardened criminals who have been in and out of prison most of their life know the warning as well as you or I. However, I came to a conclusion some years back that the warning is also a reminder to good police officers that the people we suspect of horrible crimes are still endowed with certain rights. We’re the good guys, and remembering to treat even the worst offenders as suspects instead of as guilty by our own opinions is how we stay right with the law and with the ethics we swore to uphold. Onward!

Drop the Pen! What Every Writer Should Know About Real Police Work

Writers often bend the rules of law enforcement for the sake of storytelling—but understanding real-world search warrants can help you break the rules with purpose. In this post, we take a deep dive into how search warrants actually work, so your mystery or thriller stays legally sound (or knowingly rebellious).

Search Warrants Under a Magnifying Glass

By D.L. Williams


My wife and I watch a streaming series called Joe Pickett about a game warden solving homicides in Wyoming, based on the exceptional novels by C.J. Box. Game Warden Pickett is an honest cop, savvy about woodcraft, less so about the politics and back-door deals of the world. He evidently patrols the most dangerous forest in the world, because someone ends up murdered in every book in the series and in each season of the televised program. 

I have to suspend some disbelief when I watch the show, however, because our good Game Warden Pickett seemingly has never heard of a search warrant. He’ll go in any tent, rifle through any pickup truck, and stick his nose in just about any hunter’s cabin if it means finding the truth. Our hero is out there in the woods alone, except for the fauna he protects, and lurking bad guys. Leaving a possible crime scene in the woods to get a judge to sign a search warrant for an ominous tent or a suspicious backpack means evidence might disappear and murderers will get away. 

Which is an understandable dilemma, but in legal terms this is what defense attorneys call a “no-no.” How you tackle the gray areas of fictional law enforcement depends on what you’re writing, the circumstances in the case, and your own literary voice. My job is to make sure you know the rules, so that you’ll know the stakes when you opt to break them. 

Search warrants are by far the most asked about topic I receive when writers reach out for feedback on their mystery/thriller novels or screenplays, or when I’m speaking at writers’ conferences. Writers know it is a subject they need to get right before sending a novel to agents or publishers, but high school civics was a long time ago for a lot of us. A review is in order.

Search warrants are a fundamental part of our governmental system of checks and balances. They’re a safeguard against executive branch overreach into places any reasonable person would consider private including homes, cars, computer hard drives, cell phones, and even our own bodies. We didn’t like it one bit when British redcoats kicked in our front door and rummaged around looking for evidence that we hadn’t paid a stamp tax or for contraband rum just delivered by the friendly neighborhood smuggler. So, way back in 1791 we passed and ratified the Fourth Amendment to guard against such intrusion:

The right of the people to secure in their person’s, houses, papers, and effects shall not be violated, and no warrants shall issue but upon probable cause, supported by oath or affirmation, particularly describing the place to be searched, and the persons or things to be seized. 

Which means, if police officers want to enter your home or other places you consider private, they can only do so with a warrant they’ve obtained by swearing to a judge that what they’re asking to search has to do with a criminal investigation, and that the evidence they’re basing that request on applies directly to the case. There are no search warrants granted for “gut feelings.”

There are a couple of exceptions to the warrant requirement. The first is for the owner of private property to give permission for officers to search the item or place in question. It’s kind of like the rule for vampires. Cops can’t come in until they’re invited. The irony of that analogy isn’t lost on me. 

The other way police officers can enter private property without a warrant is through exigent (emergency) circumstances. Such circumstances allow police officers to enter a private place if there is a reasonable concern someone within is hurt and needs emergency medical care and/or there is an immediate threat to lives or evidence posed by some thing or some person within the home. 

Let’s say a woman calls 911 to report violence in the apartment next door. She can hear a screaming female and a man growling threats. The sounds of glass breaking and furniture toppling reverberates through the apartment walls, and the caller frantically tells the dispatcher, “The cops better hurry before somebody gets killed.” 

Responding officers arrive in time to hear the violence still occurring within the apartment, so they will enter the domicile based on the exigent need to stop the violence and prevent further harm. Once inside, they spot a woman unconscious on the floor, bleeding from a head wound. EMS will be summoned, and first aid will commence. 

Meanwhile, the angry man heard by the 911 caller is nowhere in sight. It’s plausible he’s hiding in the apartment, which poses a continuation of the exigent threat. Officers will keep looking for the other party until they’re sure everyone in that apartment is accounted for. 

In our scenario, two officers searching for the suspect walk into a bathroom, only to discover there is a methamphetamine lab bubbling in the bathtub. This discovery will result in a whole new direction for the investigation, but for now the focus remains on scene safety. 

Only after the scene is made safe and the injured woman is on her way to the hospital will the new investigation into the meth lab kick into gear. Narcotics officers will be called in, as well as fire department personnel, to mitigate any danger from a fire or an explosion in the illicit lab. The scene will get quiet, because there isn’t much else to do until a signed search warrant arrives. Anyone still inside the apartment will be ushered out, and uniformed officers will be stationed at entrances to guard against someone going back in and tampering with evidence. 

A detective will then write a search warrant affidavit. The affidavit is designed to tell a story about how the investigation came about in the first place, what evidence has been secured in the case thus far, why the investigators believe there is more evidence to be discovered, and how they plan to go about finding it.  The affidavit in our case, for example, would detail how officers were dispatched based on a frantic 911 call, that the officers intervened to stop violence, that a man suspected of rendering his wife unconscious hid from officers, and that officers searching for that man in the apartment spied a meth lab during efforts to find him.

The detective writing the affidavit would then spell out exactly what the department personnel will be looking for as they search. Such a list in this case would include supplies used in the manufacture of the drug such as chemicals, heating elements, measuring cups, beakers, etc. 

Once the affidavit is completed and edited (yes, cops edit each other), an investigator must find a judge to sign the warrant. This can be a chokepoint if the judge is currently presiding over a hearing or trial, or if circumstances of the case necessitate the warrant be signed in the middle of the night. Most judges are patient and personable. A few are arrogant jerks, but detectives learn quickly who to approach and who to avoid when going to get a signature. 

The “Affiant,” is the person making the request of the court.  The detective affiant in our fictional case must raise her right hand and swear to tell the truth during the meeting with the judge, an oath which carries the same perjury consequences as a witness at trial if that detective lies. Most judges ask investigators to tell the story first, so they have some idea of what they’ll see in the warrant affidavit, and then they’ll read the actual document. This can take a few minutes, so good detectives steel themselves to wait quietly while the judge reviews their work like a tenth-grade English teacher reading your “What I Did Over the Summer” essay. 

The judge will sign two documents. The first is the affidavit, which spelled out the story in detail. The second is the warrant itself, a comparatively sparse document that simply says officers from Department X are allowed to search the apartment during a specified time period for the purposes of a criminal investigation. The actual details beyond the general nature of the crime being investigated are left off the document. Officers must show the actual warrant to the property owner (the Respondent), but they can withhold the affidavit with all the juicy details for now in order to preserve the ongoing investigation. All the facts will be shared with the suspect and his attorney later, but for now it’s best to keep some specifics secret as detectives work to find witnesses and other related evidence.

The apartment springs back to life as soon as the warrant arrives on scene. By then, everyone on the investigative team will know their assignment. Crime Scene Techs will start the process of photographing and collecting evidence (we’ll go into greater detail about this in a future column), and investigating officers will go to assigned or agreed upon areas of the apartment to search. 

Evidence will be photographed and labeled before being sent for processing (DNA, fingerprints, identification of unknown substances, etc.). The search will continue until the lead detective on the case deems the team has completed the objectives listed in the warrant. A copy of the search warrant is left in plain sight, often on a coffee table or kitchen counter, along with an inventory sheet of everything taken from the home.  

Now, let’s say the investigating officers find a computer in the apartment. That computer will likely be seized as well because it may contain evidentiary information such as search engine research into how to make methamphetamine, lists of ingredients needed for such manufacture, emails to and from potential buyers or sellers of contraband, and even photos of the suspect smoking or injecting the product they created. 

My recommendation is always to get an additional warrant for things like computers and cell phones. Yes, you might be covered in some jurisdictions based solely on the search warrant you gained for the crime scene. However, any evidence discovered in the computer will be challenged in court if there wasn’t a warrant specific to that private area. It’s prudent to simply get another warrant for each additional place to be searched. This would apply as well to remote storage buildings owned or rented by the suspects, cell phones, and cars. 

Novelists and screenwriters often take liberties when it comes to criminal investigations. You may choose to do that as well, if a bit of fudging better fits the tone and narrative of your work. I’m just here to make sure you know the background so you can make informed decisions as you plot your future bestseller.  I bid you luck and joy in crafting your own literary murder forest, packed full of dangerous, two-legged beasts and riddled with places to hide a body.  Onward.

Drop the Pen! What Every Writer Should Know About Real Police Work

A retired detective turned writer reveals the most common mistakes authors make when writing cops—and how to avoid them. From evidence mishandling to Hollywood tropes, here’s how to get it right and honor the real work behind the badge.

Stop Making Real Cops Cringe

By D.L. Williams


I met my wife at a murder trial. She was a journalist covering the hearings of a man who’d blasted a guy and his girlfriend for stealing his favorite gun, and I was a detective who’d worked on the case. I wasn’t the lead in that investigation, but I’d found the bullets matching the caliber fired from the murder weapon, along with a picture of the suspect holding his treasured “street sweeper” shotgun in his best gangland tough-guy pose, while helping out on the search warrant. 

I remained composed during cross examination when I spotted her from the witness stand, but she was flipping gorgeous. It took concentration to testify about the laundry-piled, old shoe-smelling closet where I’d found the ammunition and photograph, all while thinking about those eyes and the cute way her hair was tucked behind her left ear. Police work can be so rough.

Hollywood makes it seem like detectives hang out after their testimony to watch the drama through the remainder of the trial, but reality is that caseloads generally demand we go back to work on that stack of other cases waiting on our desks. That day, however, I stuck around, hoping for a chance to meet the woman taking notes in the second row. She was the consummate professional, however, and would have little to do with a cop involved in a case she was covering. It worked out, though. Sometime later we had lunch…and grandkids. 

Recently we were watching a mystery on one of the streaming services. It was more cozy than thriller, not our usual fare, but we like the lead actress from previous series and decided to give it a try. The storyline follows a civilian employee working for a metropolitan police department who solves a murder case by scrutinizing a conspiracy board when all the cops had gone home for the night. Think of a brilliant but flawed Matt Damon staring at a wall of math while holding a push broom, the only one able to solve the equation in Good Will Hunting. 

The show was fine until the middle of the second act when the protagonist was chastised by her detective mentor for taking items out of an evidence locker without permission, ferrying them to her own home so she could have a closer look, and then allowing her precocious ten-year-old son to help her sift through said evidence to get his take on things. The only question for my wife and I at that point was who was closer to the remote. 

Last year I was asked to read an Advance Review Copy for a mystery/thriller author. The story involved a street-savvy investigator, yet the protagonist routinely performed in ways that made him appear naïve. One glaring instance had him realizing his gun had been stolen, and he presumed the murderer was now in possession of his one and only available weapon. Despite this, he continued on to confront this shadowy menace without backup or a weapon of any kind. We get it; he’s a tough guy who doesn’t need any help and moves faster than bullets. He’s also an idiot. 

That kind of decision is counter to any logical response, yet the character had been nothing but disciplined and well trained up to that point. He was not thinking like a cop anymore, and many regular readers of mystery or real-life criminal justice professionals would raise an eyebrow and move on to the next book in the To Be Read pile. 

Readers and viewers may suspend some disbelief over iffy police or investigative practices for a cozy mystery, less so for darker thrillers, and not at all for police procedurals. It’s perfectly fine to fudge a bit while creating red herrings and crafting unusual characters. What is not okay is to simply omit or obscure good procedure for lack of research or to spackle over a plot hole. Frankly, it comes off as lazy, unimaginative, or a bit desperate. 

Oftentimes this creates work that feels like a copy of a copy, as if the writer learned all they know about police work from other writers of mystery or from watching old cop shows—lots of “just the facts, ma’am,” and “ten-fours,” but very little in terms of well-researched practice. 

This would never fly in historical fiction. Readers of that genre demand well-researched details in novels and films, and they tend to be something of experts themselves when it comes to a specific historical period. Writers of mysteries and procedurals should rise to at least that level of expectation when it comes to their own projects. 

You don’t have to be a beat cop or detective to write good mysteries, but you owe it to the story, your readers, and your own reputation to better understand the culture and practices involved. Unconstitutional searches and seizures, derivative suspect interrogations, and clueless practices by experienced professionals scratch across prose like a record needle bouncing over vinyl tracks. 

Of course, that may be exactly what you had in mind if you’re developing a sinister or incompetent cop character. You may want to portray a detective as inept or corrupt, in which case folding an unconstitutional search or an abusive interrogation into the storyline may be just the direction you need to take. Even then, I encourage writers to cultivate an understanding of how cops think, the mindset of predators, and basic victimology. The result will be more nuanced and compelling character arcs.

I hear from writers across the country asking questions about specific passages in their stories, and I’m always honored to discuss ideas on how they can generate more authenticity into their works in progress. They often lament what they perceive as a lack of resources for learning more about police practices and culture. Many have a great premise but no clear direction on how to make the story ring true. 

There are many books on the subject of professional police work and best practices in criminal investigations. My suggestions for getting started include Criminology Goes to The Movies (Nicole Rafter and Michelle Brown), Walk the Blue Line (James Patterson), and Malicious Intent: A Writer’s Guide to How Murderer’s, Robbers, Rapists and Other Criminals Behave (Sean Mactire). 

Additionally, I encourage you to explore writing conferences offering speakers on topics related to the mystery genre. Time and finances for travel don’t need to hold you back. There are several online seminars devoted to teaching real police work for authors. Writers’ Police Academy, for example, offers an online version of their in-person conference. Better yet, go directly to the source. 

You may already know a cop or have access to one by a degree or two of separation. Set up coffee or lunch and pick that officer’s brain about scenes you’re crafting. Certainly, ask them questions pertaining to your plot, but I encourage you to take things a step further once you’ve developed some rapport. At that point you can try to open them up about their scariest day, a case they’re most proud of, or how they came to the profession. You’re likely to be amazed, and your notebook is going to be filled with new, adventurous ideas on where your story or series can go next. 

Consider riding along with a local police or sheriff’s department. Many agencies welcome members of the community to ride out with a patrol officer or deputy, allowing you to see, hear, smell, and sense real police work up close. The officers picked for such assignments tend to be more experienced, and most have demonstrated a willingness and ability to talk about their profession in vivid and frank terms.

Explore a citizen’s police academy if you want an even more immersive experience. This is a modified version of a real academy where you get hands-on experience with forensic techniques, clarity on constitutional concerns related to policing, a sampling of various services offered by the department, and some self-defense and firearms training. You’ll have a ball, make new friends, and add experts to your writing network.

I was an English Lit major, which means I wrote good police reports (extra points if I could work in a metaphor). It also means I will forever be in awe of great writing. I feel kinship with and reverence for storytellers and want each of us to rise beyond our own perceived abilities. The expectation I hold for myself is that I will treat our craft with the same discipline as a surgeon would for medicine or a dancer for music. That means we’re in a practice, where we acknowledge we will never learn enough, yet we can never stop trying to learn more. 

Writers shouldn’t prescribe paths for other writers. Voice is all about telling our stories in our own cadence and combinations. That said, I’m asking you to honor my former profession by learning about it, then honor yourself and your work by weaving what you’ve learned into extraordinary stories we celebrate and remember. Onward!
