I already said in this post.
Or,
you can listen to people like this.
But this is ridiculous. People should not actively take gangs side.
Why not? It's much better for their physical safety, and without that, they have absolutely nothing.
No, it's not better, associating yourself with a gang is a a sure way to get killed by a rival gang.
Not true at all. That's not even true of the actual members, actually - lots of them end up living to a reasonably old age. The guys who just associate with them - hanging out, DJing, making tags, whatever - get some of the protection, and can usually scram if they *do* end up in a war.
You're still thinking about this like you're in some nice, peaceful suburb, when some assholes move in and start making trouble. That thinking isn't going to work.
This is where you can expect the cops to not help you if someone beats the shit out of you in the street and robs you. The cops either go from one emergency to the next, or they're rolling around and just harassing kids at random to keep their arrest numbers up. You're trying to fix the system, and you don't even know what system your working on.
Policing is not a cause, it's an effect. Nothing will change if you keep barking at the wrong tree.
That's not how it works, either. When you're locking kids up for dime bags and the like, you're basically making them unemployable, which pushes them to off the books stuff. Drugs, repair work, babysitting, and the like. Or just sitting around all day. When you're shoving random kids around for "loitering" and other broken-window crap, you're simply irritating them.
We lock up all the fathers by force, and then go to the neighborhood and say "Where are the fathers?" Uh, in the prisons where we put them for stupid minor offenses. If we'd stop doing that, the fathers would generally be trying to take care of their kids.
Go after the murderers, the spouse-beaters, and the like, stop arresting people and putting them on trial because they couldn't pay some citation or other. Dump all the military surplus, hire more detectives and beat cops. Figure out who the gangs are, tell them that you know who they are, keep a close eye on them. Work *with* the community to do so.
And, at least, end the "war on drugs", even if you don't entirely legalize everything.
