Look Tracker, I agree totally agree that your mayor is doing an excellent job, so why he's wasting his time and that of others having his police officers make people pull up their pants, is not that productive. I understand that everyone believes it is only a gang thing, but it's not "only" a gang thing.
The young man that robbed me in front of Caliente's was a nice looking clean-cut fellow, with his pants fully up. The police officer that he ran by said "no, I didn't see nobody run by me".
Quit worrying about the da*n pants, and get the police clued in, arrest the bad guys, get good law inforcement. Get the police properly trained and then there will be more than a clue given because of pants. Keep the "colors" off, yes, that's a gang thing.
