Well, kids in that class may behave better now.I don't know what led up to this. He could have said, Either you are going to walk out of this classroom with hand cuffs or I will cuff you. If you do not cooperate, I WILL wrestle you to the floor if I have to and cuff you. Do you want me to do that in front of all your classmates? With the video recorded devices on so many phones now, he could also have picked up her desk, as big as he is, carried her outside of the classroom and away from cell phones, and then wrestled her out of the desk. He didn't have to do it that hard, IMO.I saw a video of some big teenager terrorize a small lady teacher, ordering her to sit, hovering over her and threatening, while a female refused to sit down when she told her to. She kept asking for someone to get security. If I saw that clip and I were principal, I'd probably expel the kid.I am a very peaceful laid back guy, but I could see that I could have to potential of getting in a fight with that 16-year-old if that happened to me. If I were that teacher, I think I'd get a tazer and just taze a student that big if he threatened me.There were only a few students in that class. My guess is she was in a 'special ed' class where they put not only the kids with mental retardation, but also the ones with severe behavioral problems
