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!

Men Writing Women

When men write women, things can get… weird. In this post, female authors break down the most common pitfalls, offer honest advice, and share how to create complex, human characters—not clichés in lipstick. Because breasts are not personality traits.


You’ve seen it before. 

You may even be familiar with the Twitter hashtag or the Subreddit. But before you go too far down those hilarious rabbit holes, let’s chat with some women writers about the main pitfalls they’ve seen when men (sometimes honestly trying their best) write women characters and what they can try to do better.

While it would be easy (and hilarious) to pull screenshots or quotes from the multitude of examples where this has gone laughingly wrong—women “holding in” their periods for greater effect, for instance—in this piece, we’re going to attempt to give some honest advice to the men trying to be better. (Although I can’t promise not to include screenshots as illustrations.)

A few general thoughts to remember:

  • Women are not usually fascinated or even preoccupied with their own breasts.

  • Women are not as visually motivated as men when it comes to sex.

  • Although society has deemed it more acceptable for a woman to express her emotions, most of us do not cry all the time.

  • Women have no control over the flow of their periods.

Now that that’s out of the way, let’s address the nuances of the typical #menwritingwomen pitfalls. “Put [your women characters] in heels and makeup if you choose,” says Audrey Lee, author of The Mechanics of Memory. “But don’t lead with their stunning beauty or, conversely, with their wish to be stunningly beautiful while comparing themselves to other women.” A major complaint that many of the women I talked to voiced was that often women are boiled down to their looks when written by men. And yes, we do want a mental picture of the character, but one tip is to check how you’ve described the other characters in your manuscript. Are the women the only ones getting their body parts in print?

“Limit physical description. Let your readers fill in the blanks,” advises J. L. Delozier, award-winning author of The Photo Thief, Con Me Once and the Persephone Smith thriller series. “It’s more fun that way for the reader and you avoid landmines that way. Never describe a woman’s breasts. Ever.” Once again for the people in the back. EVER.

“Tame the body parts references!” Agrees Melissa R. Collings, author of The False Flat (Coming in 2024). “Women don’t think about their breasts during a conversation. To women, our body parts are not novel wonders, they’re just body parts.”

Now let’s address the emotional elephant in the room. Women are often perceived as more emotional than men, which can lead to one of two undesirable outcomes: 

  1. The woman who cries at the drop of a hat. 

  2. The woman who’s “not like all the other girls” because she doesn’t cry at the drop of a hat.

It’s okay to have your characters cry, but almost every human who feels the urge to cry will try to repress it at first, sometimes successfully! Even in Ghost Tamer, which is a very emotional book about grief and loss, I pulled back on Raely’s actual tears, consciously limiting her crying scenes, and she fought against the emotion the whole way. (She is also pretty funny, in my opinion.)

“Make your female characters dimensional and complex,” says Lee. “Give them a depth and drive that comes from a universal human experience. Make their emotions, insecurities, and high EQ an asset and not a personality flaw that needs fixing.” Women are, first of all, humans. And every human has experienced every emotion by the age of ten. We may not have had the same experiences, but we’ve all experienced some kind of loss, grief, love, happiness, et cetera. My personal advice is to write the human first, and then see what additional information is needed. 

“Run it by a woman if need be and check yo’self!” advises Collings. 

“Avoid tropes – the voluptuous femme fatale. The perky—God, how I hate that word—best friend. When in doubt, ask a female friend/beta reader if your female character rings true,” adds Delozier. This is sound advice. Would you want to be condensed down to a stereotypical, football loving, beer guzzling, insensitive, inattentive Homer Simpson caricature? Get a woman friend or colleague to fact check you. And not a romantic partner or your mother. They’re too close to you and have a higher probability of empathetically reading the ‘intent’ behind your words. Get someone who can be objective. 

Jackie Johnson, author of Bladestay also advises against adding women characters who “exist only to move the plot of the male character forward.” She suggests checking the Bechdel and Mako Mori tests to see how you’re doing there.  

Writer MT Cozzola has some practical advice. “What I really think about is how we can all write better characters whose identity markers are different from our own. I’d advise the same thing to myself when writing male characters: start with a bias dump—and make it specific.” Cozzola advises just listing out everything that comes to mind when you think of the character, on your own, never to be viewed by anyone else, and then just check it over for stereotypes or think objectively about how it might hit. “Once I have that awareness, I can make more specific choices about this character’s situation, which drives the way they speak and think on the page.”

Overall, you’re striving to make your characters well-rounded human beings that your female readers can identify with and root for. Not another caricature that takes them out of the story, has them rolling their eyes, and taking a screenshot to share on Twitter. 

And if you’re curious about how our periods work, just ask us. (In a respectful manner and not while you’re drinking and hopefully we haven’t just met at a bar. Jesus.)
