Something I've noticed in a lot of police encounter videos: there is no attempt at de-escalating the situation. The shooting of Daniel Shaver is a prime example of that: a benign situation made deadly by high strung officers shouting and giving conflicting orders to a stressed, innebriated man. I get that they shot because it sorta looked like Shaver may have been reaching for a gun while he was stumbling, but that whole situation could have been avoided with some simple deescalation techniques.
Is the lack of interest in deescalating situations due to training or mentality or the wish to maintain authoritative appearances or some other factor I'm not thinking of?
