respond with EQUAL (NOT GREATER) force - Example - no matter what even if the officer is loosing the fight - you don't even consider taking out a gun, if all your "suspect" has is his fists, or a knife - if they have a knife, then I whole say the cops can use a knife, but one about the same size, exc. (basically, have them bound to "fair fight" that also means no 5 people for one person - solely one on one if it gets to that point - except if the suspect has friends - but then if they don't help - basically, one cop for one person period.
Without any thing to Prove it was necessary, I believe the cops, or cops that did it, ought be personally civilly liable, and no way to get out of it. (Basically something even more unforgivable, even through bankruptcy than a student loan is. - AND I said personally, so it's the individuals not the department that takes the fall. BUT that's just the start - also perhaps criminal charges......
Now I don't know your situation, but that in general is my view.
I recently saw a report in a court where a security against has accused of sexual assault while preforming a search - fort of besides I don't believe in any search anywhere without a warrant (way I avoid a lot of places) obtained with transcript so the warrant itself can maybe be tossed later (and there by any "evidence" obtained by it dose not exist) - above and beyond all that - they arrest that woman but not the cop accused - THAT IS REPRESENTABLE.
Anyone else would have been picked up right away just because someone said that, - that cop should have been treated absolutely the same way they would treat Joe Blow accused of the same thing! - There can't be even one exception ever, or the whole system is corrupted as far as I am concerned!
