The idea that cops respond with reasonable force in a rational manner is a fantasy. They are not some innocent victims of misunderstanding, they regularly fight back with as much force as they are allowed to employ, and if noone's watching a whole lot more. It's part of their dichotomous mentality. There is tons of evidence for the idea that cops regularly appoint themselves judge, jury and occasionally even executioner. Having the right information means nothing if your entire mindset is bent around the idea that you're there to mete out punishment to the deserving and all you're doing is waiting for someone to stick out their neck to be made an example of.
Again, I am not trying to argue whether too much force is used too often or not. I am simply stating that, even if we lived in a world where reasonable force was used every time by police, we would STILL have cases of citizens being harmed by the use of force by police. Since we know this, we can't use the fact that someone was injured by police to be our yardstick for determining if a police officer did the right thing or not.
