Because gang members never end up joining gangs because of dire economic need, nor can they be rehabilitated \s
Sure, "community service" might be a poor way to rehabilitate a long-term gang member, and some more extensive process might be needed to re-introduce them to society. But I wouldn't take it as far as saying nobody should ever feel sorry for them or that justice should seek to punish them instead of rehabilitating them. In fact, it seems to me like a tracking bracelet would be quite reasonable at some point in this process, since it would make them a liability for other gang members and thus help keep them away from that environment.
