They’re all cowards. They don’t shoot black kids on their steps in a panic, they’re watching them, observing them, mulling over if they should kill them. They don’t shoot people in robberies or public mass shootings in a hurry either, they’re cowardly lying low, biding their time, doing the world’s dumbest calculations in their minds what their options are. The only reason they actually kill anyone is they think they can get away with it.

Their reflex is cowardice: hiding, running away, waiting to see if someone else does anything.
