1st, the second a weapon is used in a threat you need to immidiatly go to the police and file a report. You have past tape recordings, things are simply going to be on your side in this issue but you have to go get the Police involved. Effectively, if there is no report then it never happened.sounds like you are doing the right thing, just a suggestion though..maybe some martial arts training would help him out in the future?? i`ve been in it all my life and all my kids have been in it and are all black belts(some 2nd degree) and my oldest an instructor. not to say they go around beating up on everyone, it`s usually the opposite because after a few scraps the other kids know to leave them alone and they look for someone else to pick on. of course this isn`t an instant fix but may help down the road??? it will also build confidence and self esteem that they will sometimes lose after being picked on. just my .02
+1 on the martial arts though. I've been in allot of fights as a kid and even into adulthood. I still remember never being able to walk away from a confrontation, but with my martial arts I learned that it's allways the stronger road to take. Definitly a good thing to teach any kid and it brings a definit level of confidence! Also for those confrontations that I couldn't walk away from, it helped having a black belt in Judo
