Scope of a Search When Executing a Search Warrant
USA v. Evans, (3d Cir. 2026) May 19th 2026
In United States v. Evans, officers obtained a warrant to search a New Jersey hotel room for evidence connecting its occupant to illegal firearms. During the search, a detective noticed a piece of broken ceiling tile sitting on the bed. Standing on the bed, he pressed on the damaged tile, causing a loaded pistol magazine to fall from the ceiling. Searching the area above the drop ceiling, officers recovered duffel bags containing drugs, cash, and other incriminating evidence.
Evans argued the search exceeded the warrant’s scope. The 3rd Circuit disagreed, holding the ceiling space was a reasonable place to search for the items listed in the warrant. The damaged ceiling, the fallen magazine, and Evans’ opportunity to access the area all supported the detective’s decision to search the ceiling cavity.
A search warrant authorizes officers to look anywhere the listed evidence could reasonably be hidden. As the U.S. Supreme Court explained in United States v. Ross (456 U.S. 798, 824 (1982)), the scope of a lawful search is defined by “the object of the search and the places in which there is probable cause to believe that it may be found.”
The principle is straightforward. A warrant for drugs, firearms, ammunition, cash, or documents may justify searching drawers, backpacks, crawlspaces … and the space above a drop ceiling. A warrant for a stolen refrigerator likely does not.
That’s precisely why the search in Evans was upheld. Firearm accessories and identifying evidence could reasonably have been hidden above the ceiling tiles.

What your tattoos, your stickers, and your t-shirts say about you as a L.E. professionals?

What your tattoos, your stickers, andyour t-shirts say about you as a L.E. professionals?
Exhibits 1 thru 14 were photographs of the defendant officer who was being sued for excessive use of force with his police dog. Many of the photographs appeared to have been copied from social media posts and all of them had graphic designs relating to police dogs or law enforcement in some relatable way. The line of questioning during the defendant’s civil deposition went something like this…
Officer, do you recognize the arms and tattoos in this photograph? The officer answers, yes, these are my arms and tattoos. Are any of your tattoo’s numbers and if so, what do they mean? The officer affirms that there are vertical hashes which represent one number for each. The 5th line marks across four vertical lines to represent 5 in total for easier tabulation. The next question was, how many do these lines total in number? The officer replied, 57, then chuckles and says, “I am starting to run out of room for more.” The plaintiff’s attorney asks, what do these numbers mean? The officer answers back, “I have one for each dog bite that I’ve had with my police dog.”
The next several photographs were of stickers on the back of the officer’s laptop while it was mounted in his police car. The graphics were of aggressive dog heads, showing their teeth, a cartoon sticker with a police dog holding a severed human arm. More photographs depicted T-shirts that had the same types of graphics. One shirt had “TSGB” on it and the plaintiff’s attorney asked what that meant. The officer said, it means Talk Shit Get Bit.
I’d like to suggest to you, to consider these things from the perspective of someone outside the law enforcement profession. How do you think people might react and what opinions of us do you think they might have of us when they see these things? Our thoughts are expressed openly and displayed publicly with pictures and phrases written on the things that we wear and use daily. I would encourage you to represent yourself and the rest of us more professionally and less controversially.
These photographs/exhibits were introduced to the courts during this litigation for the exclusive purpose of demonstrating the mindset of the officer. He was keeping track of his bites by marking each one as a tattoo. The officer was keeping score and celebrating police violence to boast about the number of police dog bites he was getting. Most of our citizens have very little or no contact with police officers during their lives. The legal scrutiny that comes from the sayings on the shirts, stickers and tattoos can easily sway the opinions of people who sit on juries and judge your behavior.
K9 handlers and supporters argue that the sayings and images should be taken lightheartedly and at worst, just dark cop humor. Violence is simply an inherit part of the roles that the patrol dogs provide in real life situations where violence is met with violence to enforce the laws, some might argue. One side argues that the K9 aggression is a de-escalation method, and the shirts warn of the known consequences of committing criminal violence upon our citizens. Civil rights advocates call them a representation of a “brutality culture” and a promotion to glorify excessive force with police dogs.
I’m a retired police officer with more than 3 decades of police dog experience. Make me understand your thinking behind the shirts, stickers and tattoos. Be prepared, learn to articulate your thoughts, your opinions and your decisions.

Make me Understand : Why you used the Breaker Bar
THE RELEASE FROM THE BITE- Plaintiffs often list the technique law enforcement canine handlers perform to cause their dog to release from the bite on the suspect/plaintiff.
As an expert witness who has read thousands of police reports and supporting documents in criminal and civil cases dealing with law enforcement canine apprehensions and use of force, I’m able to see how plaintiff’s attorneys and experts view and opine on the actions of canine handlers during deployments.
In this blog series I’ll share some of these ideas and opinions which lend themselves to supporting their assertions of the Fourth Amendment infringements on behalf of their clients from my personal experiences defending the actions of law enforcement canine handlers.
THE RELEASE FROM THE BITE- Plaintiffs often list the technique law enforcement canine handlers perform to cause their dog to release from the bite on the suspect/plaintiff. I’m seeing more cases where handlers use the “breaker bar”. While there are many other things written into the complaints, I’ll just focus on this one.
1) The plaintiff’s complaint to the courts will often be that the use of the breaker bar was a requirement just to get the canine to release the bite, thus causing the bite to continue while the technique was applied.
2) The plaintiff’s experts will sometimes opine that the use of the breaker bar is an admission that the handler has no verbal control over their canine and is forced to use the breaker bar as the only way to get the canine to release.
3) The plaintiff’s experts will sometimes opine that the use of the breaker bar causes the canine to bite harder and shake their heads violently, which caused more pain and physical damage to the flesh of the plaintiff/suspect.
Many times, video footage of the apprehensions are used by the plaintiff’s experts in support of their opinions, but “there’s always more than one way to look at it”.
Good report writing by canine handlers can support their actions when using force to make and arrest. Providing the readers of these reports with your thoughts before and during canine deployments can help build a clear foundation when the camera footage is watched. These aren’t just random thoughts, but rather the details of how and what information you received and how it supported your decision to use the canine as use of force to apprehend.
To further this process of explaining what led to you using the canine, it can also be helpful to document in your report what information moved you to release the dog from the bite when you did and why you believe dusing the breaker bar was the most appropriate method.
Here are some ideas for documenting in your police reportswhy you used the breaker bar.
1) Your training with the canine on different methods for the release might help support the use of the breaker bar.
a. You’ve trained with the verbal command(s) forthe dog to release.
b. You’ve trained with the “lift off" where the dog is held by the collar with pressure on the dog’s neck to restrict breathing.
c. You’ve trained with the breaker bar.
2) Have you had experiences with all these types of bite release techniques in various training scenarios which give you an idea ofhow the dog will react when each is applied?
a. Have you been trained in various situations that have helped you understand that physical control of the canine up close, including holding his collar with your hand might be the best option when considering the safety of others and the suspect during the release from the bite? Have you been trained or have you learned through other experiences that canines that are in a high state of aggressive arousal might mistakenly bite again when removed from the bite?
b. Would those experiences and training make physically holding the canine’s collar while applying the breaker bar make you know that it’s the most effective for you canine and the safest for the suspect to prevent unintentional re-bites?
“The totality of the circumstances” isn’t a phrase to take likely, it should be the reason you pause to think clearly before deploying your canine and the reason you pause again when you start formulating your thoughts about how to write your police reports. Good police reports will have clarity and move with a purpose to progress the ideas for your actions. It should be clear to the readers of your report that you understand the law and the policies that govern your lawful actions and give you authority. Those actions should be supported by the facts and circumstances that were known to you, and which helped you to make the decision about using the canine as a use offorce and then to choose the breaker bar as the technique for this incident.

As an expert witness who has read thousands of police reports and supporting documents in criminal and civil cases dealing with law enforcement canine apprehensions and use of force, I’m able to see how plaintiff’s attorneys and experts view and opine on the actions of canine handlers during deployments.
In this blog series I’ll share some of these ideas and opinions which lend themselves to supporting their assertions of the Fourth Amendment infringements on behalf of their clients from my personal experiences defending the actions of law enforcement canine handlers.
Many times, canine handlers will be questioned during depositions about the “time on bite” and be asked to explain why body camera video footage appears to show a complaint and surrendering suspect who’s still being held by a police canine. Does your police report make me understand WHY and does it comport with the videos?
It’s important to have the answers both in your written police report and be able to verbally articulate the facts that support not removing the police dog from the bite from a suspect who appears to be compliant in videos.
What you knew about the suspect, his crimes, his criminal history, his emotional history, his current emotional condition, and his current capacity or potential to escape, fight, resist, or otherwise place officers and others in imminent danger are things that you might consider important for the readers of your report to understand and to make sense of an incident that might not at first glance.
You cannot gloss over this concern nor paint it with the broad stroke of a “catch-all” phrase or idea. For example, we cannot simply write in each incident that “The dog was removed from the bite after he was handcuffed” OR “I left the canine on the bite for fear that he would injure us (officers) or escape into the neighborhood where he would be an imminent threat to citizens”. The details must support this idea and without them, your actions can be visually overwhelming and seemingly outside of the laws and your department’s General Orders.
Our society affords law enforcement officers the power to use force to make arrests, but it holds us accountable to being reasonable with uses of force and so it is expected of us to be educated, well informed and be able to articulate our actions so that we make them understand why.
Here’s a comparison example of how the circumstances and facts of an incident guide the courts in determining whether an officer is justified in their use of force with their police canines.
Here’s two different court cases with similarities but clear and distinguishable differences in the circumstances. In both cases, a police dog was used to bite a suspect, but the circumstances differ enough that they can help show the contrast between a justified use of force and one that wasn’t.
Research these two cases, Preister v. City of Riviera Beach and Crenshaw v. Lister. You’ll see from reading them that the totality of the circumstances helped support the time on the bite in the Crenshaw v. Lister case. Whereas the Preister v. City of Riviera Beach case fell short in proving the time on the bite was a proper use of force.
