Dear Sun, Hey, hard one. The only thing I ever heard of, was to get them out of the area. Clean slate, unknown, start over.

California is about to ZAP the guy ("Tookie" Williams) who started the whole gang thing way back when-- Dec 13th, unless Arnold commutes his sentence to life w/o parole. He's spent the last many years working to take the "bling" off gang life, try to head off what he srated. Written books, etc.. Seems to be a search for a sense of family and belonging, that is the first hook. They pay a high price to belong. Very sad and scarey situation. Best Luck.
