Police Use of Force: The Need for the Objective Reasonableness Standard

The public debate over police use of force continues, with some advocating legal changes. Agencies are revisiting their policies, and some are asking for public comment. This is what the Chicago Police Department did in November 2016 after posting their draft revised use of force policies. Comments posted by two law professors, Sheila Bedi and Craig Futterman, during this period will serve as the focal point for this article.(1)

Bedi and Futterman state:

The policy should delete terms such as “reasonably believes” or “reasonably necessary” because they are confusing and fail to provide clear guidance to officers. The policy should instead read: “The use of deadly force is a measure of last resort that is permissible only when necessary to protect against an imminent threat to life or great bodily injury. As such, an officer may use deadly force only when such force is necessary to prevent: (a) death or great bodily harm from an immediate threat posed to the sworn member or another person, or (b) an arrest from being defeated by resistance or escape, and the person poses an immediate threat of death or great bodily harm to a sworn member or another person unless arrested without delay.” [emphasis added]

To the average reader, this suggested policy language may appear reasonable. But it is contrary to the law and completely ignores the fact that things are not always as they appear. This language assumes that human beings – police officers – will 1) immediately have all the information necessary to them to make a decision and 2) have the mental capacity under stress to make the correct decision.

The language “reasonably believes” or “reasonably necessary” flows from the Supreme Court of the United States and the seminal decision of Graham v. Connor.(2) The court recognized that officers need to make split-second, life-or-death decisions that are not capable of precise definition or mechanical application. Such decisions are to be judged from the perspective of a reasonable officer on the scene and not with the benefit of hindsight. The objective reasonableness standard accepts the reality that officers must make the best call they can with whatever information is available to them, and sometimes that call will turn out to be wrong. The language proposed by the professors would reject this reality and make officers strictly liable should they reasonably but mistakenly perceive a threat.

Human Limitations and Inadequate Training
In so many areas of our society, we tacitly take for granted that humans are prone to mistakes when faced with rapidly evolving situations. So why do so many people fail to consider human error when evaluating police use of force?

Think about it: The existence of instant replay in professional football, baseball and basketball is an outright acknowledgment that humans are fallible. Even without instant replay, professional referees and umpires already have an advantage that police officers do not – the ability to confer and consult with each other after a call is made, and reverse the call if appropriate.

There are some who will bristle at this comparison: “The police can take a life; how can you compare that situation with a game?” But the fact that a use of force decision can have life-or-death consequences does not change the reality of human fallibility, especially when under stress. The question really should be, how can we place police officers in such critical situations and hold them strictly accountable for reasonable perceptions when we are surrounded in everyday life by the reality of human shortcomings?

“But the police are trained to make such decisions!” Oh, really – are they? Most high school athletes will receive more skills training in their sport than most police officers will receive in their entire career. In New York, we give officers about six months of basic training, which includes 40 to 48 hours of defensive tactics training, 48 hours of firearms training, and, depending upon the size of the agency and/or the academy, limited scenario-based role playing and decision making. To be generous, call it about 140 hours of skills training. Then, officers graduate and face the realities of police work in which those skills are infrequently used. As they are perishable skills, officers may not have sufficient mastery to efficiently and effectively apply a necessary skill. If we are going to start holding our officers strictly accountable, then perhaps we need to follow the special forces model and require officers to attend an additional 18 months of specialized training. This would not be a popular option in an environment where there are multiple demands upon tax dollars.

Inattention Blindness
During a recent NFL playoff game between the Seattle Seahawks and the Detroit Lions, Seattle had driven up the field and was on the one-yard line. Russell Wilson floated a pass toward the back of the end zone and receiver Paul Richardson made an incredible one-handed catch for a touchdown.

But several things happened very quickly on this play and not everything was caught by the officials. First, the defender interfered with Richardson, for which an official threw a penalty flag. After calling the penalty, the officials then focused on what they are supposed to primarily focus on – did Richardson catch and control the ball and did he land in-bounds? The answer to these questions was yes, and the play was ruled a touchdown. What the officials did not see, however, since their attention was focused on the catch, was very clear in the subsequent instant replays: While Richardson was reaching out with his left hand for the ball, his right hand was locked onto the defender’s facemask, pulling the defender’s head toward the back of the end zone. This should have resulted in a facemask penalty that would have offset the defender’s penalty, thus negating the touchdown and resulting in a replay of the down. The NFL rules, however, do not allow for review of missed penalty calls in such a situation. So, the play stood as called.

How can a highly-trained NFL official miss such an obvious penalty at such a critical moment? This is likely an example of a phenomenon called “inattention blindness,” which was originally discovered in 1975 and subsequently made famous by the “invisible gorilla” video.(3) In the video, six persons in two teams of three were passing a basketball back and forth. Team members were dressed in either a black or white t-shirt and the subjects watching the video were instructed to count the number of passes made by the team in white. During the video, a person dressed in a gorilla suit passed through the players and pounded his chest. The typical result of this experiment is that half of the study participants do not see the gorilla at all.

How can that be? The subjects were engaged in a specific search task. Our attentional load is limited, and when faced with complex tasks or situations we must decide what to attend to and when.(4) It is not only entirely conceivable, but it is also predictable that NFL officials facing a complex play, with so many different things to try to pay attention to, will miss something. Police officers, when faced with potentially dangerous situations, have the same attentional load limitations. There is only so much that they can “see,” and, as frequently happens in real-life examples, officers can miss things that are obvious with hindsight. To hold them strictly accountable by policy language will not change the reality that their attentional load is limited. And this does not even take into consideration other environmental factors an officer may face that can impact decision making, such as inadequate lighting, inclement weather and the presence of factors known to the officer entering the situation (e.g., encountering a person near the scene of a “shots fired” call).

Environmental Stress
To add to the problems of limited attentional load, there is also the impact of stress on human physiology. Professional umpires and referees work under periodic mild to moderate stress, but police officers involved in deadly force incidents are subject to extreme stress.

When we perceive a threat, a complex process immediately commences in the brain, resulting in, among other things, the release of adrenaline and cortisol. This is what prepares the body for fight or flight, a response that has allowed our species to survive predatory attacks.(5) But side effects of this process can impede an officer’s ability to properly perceive all available stimulus. Side effects of the fight or flight response include:
• Selective attention, also known as tunnel vision. There will be an immediate tendency to focus on the perceived threat, to the exclusion of all other stimuli. As a result, the officer may fail to perceive peripheral activities.
• Auditory exclusion. This is the hearing equivalent of tunnel vision. People operating in high-stress situations may hear sounds and voices as muffled or distant—or may lose hearing entirely.
• Loss of motor skills. As a person’s heartrate reaches the 175 beats-per-minute mark, they begin to lose their gross motor skills, which can compromise an officer’s ability to effectively use their firearm or apply some type of defensive tactic technique.

Some proponents of restricting police use of force advocate that use of force policies should list situations where use of force would be strictly prohibited. Again, this may sound reasonable, but once you consider the phenomenon of inattention blindness and the human body’s reaction to stress, it is not realistic to expect that any officer would be able to safely call up for mental review the list of prohibited situations and apply that to what he or she is facing. We simply do not have sufficient attentional resources to handle such demands.

Misguided Changes
Reviewing our use of force policies is a good exercise, especially following incidents that draw public scrutiny. But proposals to restrict use of force policies by eliminating any reference to the objective reasonableness legal standard are misguided and pose a significant legal threat to officers and departments. The objective reasonableness standard exists as an acceptance of the realities officers face when involved in high-stress, use of force encounters. Removing it will not have the desired effect on officer’s behavior. Instead, agencies should focus their time and efforts on providing the needed training to help officers make sound tactical decisions when engaging in certain incidents.

“It came down to three main factors for us: safety, time and efficiency. This is a way to protect  the staff, public and inmates in the best interest of all.”

Major Jeff Fox
Vigo County (IN) Sheriff's Office

“Lexipol’s Implementation Services program was key to getting our manuals off the shelf. If it weren’t for that, we wouldn’t be implemented today. Departments should recognize their limitations and realize that they likely don’t have the resources to do it on their own. Implementation Services is key to getting it done.”

Chief Deputy Ray Saylo
Carson City (NV) Sheriff's Office

"It’s a huge priority of this administration to teach policy to our sergeants, and Lexipol’s Daily Training Bulletins help us do that. We are constantly drilling into them that policy will protect them as an individual officer. If they ensure that their people are following policy, even if they’re sued, they will be OK.”

Sgt. Bryan Ward
Cumberland County (PA) Sheriff's Office

"Calling Lexipol an insurance policy doesn’t do it justice, because it doesn’t capture the enormous power that partnering with Lexipol provides.”

Chief Deputy Klint Anderson
Weber County (UT) Sheriff's Office

“We spent a considerable amount of money and effort trying to develop and maintain comprehensive and legally based policies and procedures. Lexipol has relieved us of that burden and provided us with a policy system that we have great confidence in and that we can tailor to suit our particular goals and community standards.”

Sheriff Blaine Breshears
Morgan County (UT) Sheriff's Office

“We had a use of force lawsuit, and as soon as the attorneys discovered that we have Lexipol, they said, ‘We won’t have an issue there.’ Our policies were never in question.”

Lt. Craig Capps
White County (TN) Sheriff's Office

"I would recommend Lexipol to any law enforcement agency, whether three-person or 2,000-person—it makes no difference. The program works.”

Chief John Defore
Hiawatha, KS

“By offering 365 daily training bulletins to my officers, I am saving far more than the cost of the software every year. In fact, I was able to show my commissioners a cost savings by utilizing Lexipol for our policy and policy training needs.”

Captain Jeff Schneider
Yakima (WA) Police Department

“KMS tracks and logs when people acknowledge and accept updates, which is very important, and it lets us track who isn’t getting the updates so we can give them the appropriate attention.”

Chief David Maine
The Village of Hunting Valley (OH) Police Department

“What we had before Lexipol had been around for years. It was like every other policy manual I had seen: It didn’t get the updates it needed. The Lexipol manual is a living, breathing document.”

Chief Deputy Lauren Osborne
Surry County (NC) Sheriff’s Office

“If there’s a change as a result of case law, or a procedure that needs to change, Lexipol does the legwork, sends it to us, we approve it and send it out to our people for acknowledgement—and it’s all documented.”

Sheriff Gerald Antinoro
Storey County (NV) Sheriff’s Office

“Lexipol is one of the best products I have seen in my 30+ years in law enforcement.”

Deputy Chief John McGinty
Simi Valley (CA) Police Department

“You get sued for your policies or you get sued for your actions, or both. You can only do so much about actions. But having Lexipol gives me confidence that if we draw a lawsuit, our policies won’t come under attack.”

Chief Kelly Stillman
Rocky River (OH) Police Department

“I can’t say enough about the positives from a chief’s perspective. I don’t know why everyone isn’t with Lexipol.”

Chief Jeff Wilson

Chief Ralph Maher
Oak Creek (CO) Police Department

“With Lexipol, I know our policy manual is going to be up to date. I can turn my back on it today and tomorrow there will be any needed updates waiting for me. That allows me to focus on some of the other things I have to do as a chief.”

Chief Steven Vaccaro
Mokena (IL) Police Department

“If you compare Lexipol to other policy providers, Lexipol is the only one that has policy that has been vetted by other chiefs, industry experts and lawyers. All you have to do is tailor the policies to your agency’s needs.”

Commander Leslie Burns
Mercer Island (WA) Police Department

“Lexipol provides a huge advantage for agencies pursuing accreditation. The tools take about 60% of the difficulty out of the accreditation process. If you want to be accredited, this is the way to do it.”

Deputy Chief Robin Passwater
Kankakee (IL) Police Department

“If you don’t have Lexipol, even with a full-time person dedicated to policy, there’s almost no way you can keep updated on all the laws and also have the training component. It’s an excellent system.”

Assistant Chief Bill Holmer
Glen Ellyn (IL) Police Department

“It’s a no-brainer for me. Someone is watching for changes to laws for me, and then tweaking the content based on those changes or updates in best practices.”

Lt. Ed Alvarez
Bay Area Rapid Transit (BART) (CA) Police Department

“I like the mobile app because it tells me no matter where I am when I have updates to complete or when people take the DTBs. No matter where I am, I have access. The officers can get real-time updates. Everything is at their fingertips, any time.”

Chief Greg Knott
Basalt (CO) Police Department

“Lexipol gives you peace of mind because the policies that you’re implementing have been reviewed by professionals in the field and by attorneys—not just your agency’s legal counsel.”

Chief Corry Blount

Lt. Victor Pecoraro
Auburn (CA) Police Department

“The updates are super easy because you can pop them open, see the redline versions and be able to edit it on the fly. Once I learned I could do that, I was excited.”

Chief Joseph Morris
Arapahoe Community College (CO) Police Department

“Officers are not infallible. We have limited memories like everyone else. Working under stress presents more challenges. There are times we need to access policies in the field so we are comfortable in our decision making. The mobile application has been great for this!”

Captain Jesus Ochoa
Coronado (CA) Police Department

“Knowing that Lexipol is keeping our policies current means that there isn’t something else for us to worry about. We can focus on our jobs. That definitely gives us peace of mind.”

Chief Steven Vaccaro
Mokena (IL) Police Department

“If you compare Lexipol to other policy providers, Lexipol is the only one that has policy that has been vetted by other chiefs, industry experts and lawyers. All you have to do is tailor the policies to your agency’s needs.”
