Excessive force is an interesting concept because I use it in criminal defense as a defense to certain crimes that my client is charged with. For example, California Penal Code 148(a)(1) resisting arrest and battery on a police officer (CALCRIM 945).
Some of these other charges that the police drum up once they rough somebody up and the person either fights back or doesn't fight back, the police are just putting a crime in there to justify arresting them, putting them in custody, and trying to counter any civil claim the person might have against the police.
So, the CALCRIM 2656 jury instruction that would be given has to do with saying you're being charged with resisting arrest. The officer has to be in the performance of their duties at the time. So, they can't just attack somebody or use unreasonable force and then claim that you're resisting arrest.
So, the jury instruction, which is the law that would apply at a jury trial, is that a police officer is not permitted to use unreasonable or excessive force in making or attempting to make an otherwise lawful arrest in detaining or attempting to detain a person for questioning.

If an officer uses unreasonable or excessive force in making or attempting to arrest, detain, or try to detain a person for questioning, the person being arrested or detained has the right to lawfully use reasonable force to protect themselves. This knowledge empowers individuals to defend themselves when faced with excessive force.
Thus, if you find that the officer used unreasonable or excessive force in making or attempting to arrest in question and if the defendant used only reasonable force to protect themselves, the defendant is not guilty of whatever crimes they're being charged with.
So, this is telling you that the police can't attack people and rough them up, and then when the person tries to defend themselves from being attacked, the police are going to charge them with a crime related to that.
It's difficult to prove these cases a lot of the time; however, now, with all the new video evidence available to people, it is possible to argue that the police used unreasonable force. You could also use witnesses who saw what happened if you weren't doing anything, and the police just came up and attacked you and threw you down, and all you were doing was defending yourself.
Right to Self-Defense or Defense of Others
Another CALCRIM 3470 jury instruction given with these cases when you're trying to defend them when the police have acted unreasonably is self-defense.
Somebody attacks you, even a police officer. You can argue that you're just simply trying to defend yourself. Therefore, you shouldn't be able to be charged with any particular crimes. Otherwise, that would be unreasonable and unlawful.
So, if you find yourself being charged with a crime, and you believe you did nothing wrong, the best course of action is to seek legal representation. An attorney can thoroughly evaluate all the facts and circumstances and devise the best strategy to defend you in your criminal case, providing you with the support and reassurance you need.
Primary Factors in Excessive Force Cases
All of this, though, is going to center on a couple of big things:
- do they have the evidence to prove that you somehow attacked a police officer?
- do you have the evidence to show that you didn't do anything unlawful? And then, of course, the question will be reasonableness.
Did you act reasonably under the circumstances? And did the police act reasonably under the circumstances? Sometimes, there's evidence on both sides, and these cases need to go to trial. Other times, it's pretty clear that one side acted unreasonably, and the side that acted unreasonably is the one that's going to lose the case.
