KT--- you are not right for that...
For the most part, it sounds like the teacher did not want to deal with this child and her outbursts, today... Sounds like this kid had them before, but not to this degree and not to the point that the teacher could not manage to kick the child out of the classroom to the prinicipal's office.
I think the mother lives in denial that her little "angel" is a little "hellion" in class. My mother (a retired principal of an elementary school) and my brother, as well as his wife have had to deal with lunatic children... Usually, they can be controlled by either the principal or school police.
It sounds like there is more to this story and it smells like this child is a substance abuser baby... Ain't no way she actin' like the Taz, in the classroom so much so the teacher feels threatened and calls the regular police...
Maybe this will scare the kid straight?
What if she was in an severely emotionally disturbed classroom? I could have set off the other kids in that kind of classroom.
