American police aren't trained in deescalation. Couple that with their militaristic training style and you have a tendency to be cowboys, rushing into battle in a blaze of glory. It's further complicated by massive inequality in the country, which generates strong class differences, resentment, and ultimately an "us vs them" mentality. And we haven't even gotten to the pervasive racism yet. America is an adolescent state, born from extreme violence and trauma that hasn't subsided yet. Americans in general are a paranoid people due to their general personal insecurity (high inequality, classism, racism, tribalism, one sickness from financial ruin, etc). It's only natural that their police force and justice system develop in such a medieval retribution style.
