He was being disruptive in class in at least two ways. He was screaming out for attention in inappropriate ways. At 13, he should have learned long ago that there are good ways and bad ways of seeking attention. The teacher was right to elevate this above sitting in the corner - the student needs to quickly learn the rules of appropriate behavior.
It would have been a little different, IMO, if he were say 7.
The officer was correct to interview him and release him to his mother. I hope that along the way the adults impressed upon him that he needs to straighten up. I hope she takes this as a gentle warning as well - he's too old to be acting this way in class.
I'm disappointed, but not surprised, by the news story. Too many news people seem to think that teachers are incompetent and unable to handle "simple" situations.
My $0.02.
Cheers,
Scott.
