Cops are well trained in self-preservation with little "respect" for thugs or the self-righteous.
Maybe we ought to send them over to the Middle East to train our Special Forces and Navy Seals! Judging by what I've seen and know of cops who empty their guns at car chases and only hit their target one or two times, or shoot a guy 15 more times after he's already down and not moving in a pool of blood, and tend to be rather jumpy these days, I tend to disagree. I tend to see many police as way UNDER-trained these days, projecting fear and caution and mistrust rather than warmth, and rely on projecting a strong front as a bluff because they rely upon fear as crowd control.
Whatever exactly happened here, if this kind of stuff keeps up, eventually some day, there will be a mob of people NOT afraid, against 5 armed police, or in that crowd there might be 5 armed, well-trained citizens who have simply had enough. It's not going to end well.
The police MUST maintain control.
The citizenry MUST seek justice.
There aren't enough cops in all the world to control 320 million Americans if they get mad enough, especially as they own 300 million guns and a trillion rounds of ammunition.
The FAR saner alternative to CIVILITY. Civil populous, police well-trained, certain boundaries set, and held accountable.
