I've seen some shocking videos the last few years of American cops. Got to be the worst trained police force on the planet, they just don't seem to know how to de-escalate a situation.
You are right, they seem to have no clue in de-escalating a situation, it's whatever has to be done, has to be done there and then, even if it costs a life. I'm starting to wonder if they need to start recruting fitter younger cops, if they are so insecure, that they have to keep reaching for a gun.
