So, Brooks fell asleep in his car. Some moron called the cops on him. They administered a sobriety test, which Brooks apparently failed. Seemingly, no problems so far. Instead of making sure Brooks got home safely, without posing a danger to himself or to others, so as to sleep it off, the two incompetents got themselves into a physical altercation. They not only lost that altercation, on top of that they also lost a taser. Then Brooks ran away, posing no discernible danger to anyone's life, and they still shot him dead.
So, there we have another case of "Serve and Protect" as currently understood: Being caught asleep in a car by two over-eager adrenaline junkies carries a death sentence. Quite predictably, the "Sanctity of Life" faction couldn't be any giddier.
Really. In a situation already tense with rage over gratuitous, racist police brutality, it takes a benighted moron to deem it a good idea to shoot dead yet another black man for no good reason.
