I could have been this kid back in Jr High school. I might even have done exactly what this kid did back then, if recording devices didn't weigh a ton. Yea, I'm dating my generation here.

Bullying was out of control, even back then. Its nothing new except for the media is finally covering it. I was no the receiving end of that bulling up until the day I took Aikido. My instructor was an elderly woman weighing in all but about 86 lbs soaking wet. That class change my life. I had started taking Judo 9 month earlier but it had not yet come in handy for anything. After sitting in on just one Aikido class at the ripe old age of 13, only watching, I threw and pinned my adult Judo instructor using an Aikido move in a sparing match when I was just supposed to be the practice dummy for class demonstration purposes.
Since graduating from high school, I have also taken Taekwondo, Shaolin Kung Fu, and Kenjutsu, but I always come back to Aikido in a time of need and/or a delicate situation. Its just more useful in everyday life. You merely use the opponents own energy against themself, by understanding the physiology of the human body and how it can and can not move. The philosophy of not hurting the opponent is the best part of it, and therefore useful for almost any kind of bad situation.

My last encounter with such a school yard bully was as a bystander in a high school metal shop class, only I just couldn't stand there and watch it happen. The Class Clown (aka dumb F*@ck ) took a hand full of metal shavings off the lathe and went to shove it down this one kids shirt, and my own hand wound up going in right behind. I clinched his fist so he could not let go of the metal shavings, pulled his hand out slowly, squeezing his hand with around 90+ lbs of pressure, and then gently rolled him across the shop bench table with one hand. All 200 lbs of him, while I was about 150lbs at the time. Its proof that with enough thrust even pigs can fly....
The administration, as you might guess did nothing, so the mighty sward of 'do-nothing-ever' cuts both ways at times.
A little bit of self confidence can allow you to talk your way out of bad situations a lot more easily. Simple fact, its no fun to pick on someone who is just not afraid of you. The bullies are after the feeling of control they get when someone submits to their will, and they won't get any kind of satisfaction like that here.
