What "race" is KPFT? I know most of them are in contact with something in outer space. I used to listen to KPFT for fun. It's probably considered cruel to laugh at the mentally handicapped.
Considering their location a bullet through the window may not be significant of anything other than some local dispute. Fifty years ago I lived a couple of blocks from there and it was well on it's way downhill.
That block is very yuppie liberal today. The violent crime is over on the other side of Westheimer.
