I truly feel for you as well as your sister. My biggest fears for my children are gangs and drugs, because I have seen first hand how horrible both are. I can't offer any magical solution, and it may not help, but I certainly think it can't hurt, but I have my 12 y/o son enrolled in the Young Marines. They meet every other Saturday, from 7:45 - 3:00, and I am really happy with this group. I'm not sure where your sister lives, but she can go on-line and Google Young Marines (we are in Bellflower so we go to the Lance Cpl Worley young marines). Tell her to give it a try. :) and good luck!!!!!!!!!!!!!

I also wanted to add that gangs are a family, and are tough to get out of. I dated nothing but "gang bangers" and thugs etc.. for about ten years, and all of them had the same response to the question "Why did you join a gang?" The answer was family/love, or a sense of belonging. It's also an accomplishment of some sorts. When a child feels unloved, a natural reaction is to seek it elsewhere. For me, I sought that love through men, and those men, in turn sought love in me, and I learned a whole lot from that experience. I can say to tell your sister to love him, show him love and keep him involved in activities, but the truth of the matter is, it's not likely to help. He might be close (not actually there, but close to) a point of no return so to speak. Sometimes scare tactic's work, most of the time they don't. If he is a good kid with a good heart, it will work. Play on his sensitivity, but otherwise, I really don't know what would help besides divine intervention :)
