I forgot about this post. Thanks for the replies. Thought I'd respond and update.

As much as I wanted to call police... they won't and can't do anything to kids under the age of 12 here. Even if they murder someone (though social services can enforce therapy in extreme cases like murder ) . That's the canadian legal system for you. Potentially had I invested the money into surveillance cameras etc and caught these little turds in the act I may have been able to seek financial restitution from the parents for whatever damage their spawn did... but that would have taken months and more money than the actual damage caused in this case. The bullying would not be addressed at all as far as police were concerned.

However, that said.... what I ended up doing was just randomly popping up everyday where ever my son was playing under the guise of bringing him a bottle of water (cause it gets hot in the summer playing in the sun ya know ). If these bullies happened to be where he was... I lost my marbles on them. Repeatedly. Whether I caught them picking on him or not. I think farmers in the next county over could have heard me screaming at these kids. I think all the kids in the neighborhood now think I'm a giant ***** and are scared of me. Other parents probably too. lol. But my son doesn't come running home anymore cause kids are picking on him. Works for me. I do think my son is still a little embarrassed of me. But what kids aren't embarrassed by their parents? I know I sure was!

Would still like to get him into something like martial arts just because it would be a confidence booster i think. Still working on trying to convince him to try it (or anything else like that).
