I dealt with a lot of hot head teens when I was a cop. They usually puffed up like toads when they were around each other. Kind of fed off each others stupidity. Then usually cried like little girls when you got them off by themselves. Pretty pathetic at times.
I did get punched by one once, and the only reason I did not clean his clock was because I was afraid it would have killed him. He was so small that when he stood sideways, he looked like a golf club. I was benching 315 at the time so I wrote it off to him being an idiot and settled for the battery on LEO charge instead.
Now in defense of someone small, the hardest I was ever hit was by a guy that weighed about 110 pounds. It was more my fault because I totally underestimate him and let my guard down. When I woke up, my partner had already done the Mexican Hat Dance on his head and was laughing his a$$ off at me. I had a headache for 3 days.
As far as going to jail? Never myself. Not because I did not do anything. Anyone that knows though will tell you that no one can find trouble faster than police officers and firemen. I had on many occassions been out on the town with some of the guys and managed to get into something that would bring the local police calling. It would have to be pretty bad for them to take you in. The only thing that I know that would get you arrested really fast (and I would do it myself) is Driving Under the Influence).
