Teacher Duffs Student Found Not Guilty.

Sandra Hadsock clenched her teeth, balled up her right fist and closed her eyes. The 5-foot-5 art teacher's first punch was a wild haymaker, just glancing the towering student's right cheek.
Then, as she drew her arm back again, Hadsock gripped the boy's jacket collar and leveled a right cross, catching him square on the jaw. His head snapped to the side and his mess of orange hair blew back.

Now, three weeks after the incident was caught on a student's cell phone videocamera, the State Attorney's Office has decided not to file criminal charges against Hadsock, who had been arrested on a single count of child abuse.
Hadsock landed at least one punch on the student's face, causing a minor cut on his lip, authorities said. But the video doesn't provide conclusive evidence that the 64-year-old veteran teacher wasn't acting in self-defense when she swung at the student who called her vulgar names, prosecutor Brian Trehy said.
Students who witnessed the incident said the teen made contact first and the teacher was responding to that, Trehy said.
"You couldn't put a piece of paper between them," Trehy said. "You can't tell if he actually made contact, but it's certainly reasonable to believe that it could have happened."

This is open and shut to me.   All you have to do is watch the video in the source link.  There's no way you can tell me, anybody can be expected to not react in that situation.  Dude is all but attacking her!  He was lucky she didn't know some type of skill.  I'dve died laughing if she front kicked the life out of him Anderson Silva style!

What's funny to me is when you watch the video the girl in the background talking about "you can't do that!"  What?! On what planet do you expect someone to just stand there and hope nothing happens when someone is running up on them with clear hostility?  That's what's wrong with the world today.  These kids think they can do anything they want without fear of any consequences.  All this you should never resort to violence ever when dealing with kids B.S.  Do I look like Ghandi to you?!  The D.A. got it right this time.
