One evening they pulled that in a 7/11 and one of the Indian clerks recognized them ~ so they killed him.
After months of complaint the cops finally broke up the gang, arrested them all (white, black, brown, yellow, etc.) and sent them to prison. The local grocery stores just weren't the same anymore.
More recently a black "flashmob' was operating in Montgomery county MD (NOT THAT far away). Improved security camera systems IDd a bunch and they got caught quickly.
You just can't go anywhere these days without being filmed.
THIS is your solution? A SURVEILLANCE STATE? No thanks. I will be armed, and will defend myself with LETHAL FORCE. The decent state I live in encourages it. I will pop any Trayyyyyyvon who attacks me.
And take your witch hunt for Zimmerman over to DU. It (and arguably you) don't belong on FR.
