Do you think it would be worth running your own community service for them and not pressing charges. Make them do things around the house for your mom. leaves, mowing etc.... I guess the only problem with it is that the parents would have to back you and thats out the door. Could be worth a shot
Maybe you could then turn some of these kids into solid young adults and give them a role model instead of them looking at their looser parents as role models, which they are not!
Maybe even could get some of them fishing and again having a positive role model. "Kids that grew up hunting and fishing don't rob old ladies when they are old".... read that somewhere
God i am a sucker
