Back in the late 70's an acquaintance's sister and girlfriend walked out of the restaurant area downtown Baltimore into the hood by mistake. Beaten, gang raped and one of the girls died. Learned then what the score is and what thugs do when they have the advantage.
Cops could clean that mess up if they wanted to. Send in a frail old white lady in there and stay back in a shaded window car with a shotgun and extended magazine. Like it or not it will just get worse until there is a civil war.
