Some instances I can recall as a result of this ridiculous zero tolerance BS.
Elementary age kids expelled for playing cops and robbers.
A young girl being expelled for folding a piece of paper into the shape of a gun.
Another child expelled for possession of an ibuprofen.
A poor kid who took a knife away from a suicidal friend. Told school authorities it was in his locker, and then got expelled for possession of a weapon.
The film ended with video of several cops handcuffing a small girl I'd estimate to be about 6 - 7 years old. She was crying and obviously scared to death. I'm by no means a compassionate guy, but I literally felt sorrow for her.
3 - 4 armed adults can't handle a little girl, without handcuffs?
It made me want to take a ball bat to the officers.
