I live in the deep south, this stuff is very disturbing, In the Early 70's there was a huge amount of rioting here, tanks in the street, shooting at fire fighters and of course shooting at rioters and by standers as well. Now days it would be difficult to imagine this happening here, there are still neighborhoods that are segregated both white and black but most of us live beside each other, have a beer on the porch together, look out for each other but the neighborhoods that are segregated, and it's doubtful the black neighborhoods are segregated by choice but mostly by economic disadvantages and the whites are segregated by economic advantages, are still hostile places to some extent.
Two nights ago i was leaving the hospital late and took a short cut through one of the "wealthy" neighborhoods and at a stop sign i suddenly found myself lit up like the midday sun, in that neighborhood there are few street lights and fewer cars at that hour. a police helicopter followed me for two blocks until i left that area.
Sometimes i think the world has gone crazy, I wish it had been a UFO, at least that wouldn't have made me feel like a roach running across a lighted room...
