You posted, “Hmm... Blacks do this to other blacks, you know. It’s not just confined to white victims. I was jumped by gangs of black hoods twice in my teen years, and I’m black.” Glad you were not permanently injured.
True, that this is not only black on white, but also black on black, black on Hispanic and black on Asian.
In this particular area of Denver, the police are aware that there is a gang problem. Why the hell not have a plain clothes “sting operation”. Some cop acting as a drunk but with plain clothesmen ,and women of course, close by and watching.
Bait the bastards up and nail them.
It'd never fly in this pc-mad country. There would be lawsuits and press conferences by Jackson, Sharpton, etc. flying all over the place.
