Abusive bus driver

On some buses they have been putting up cameras and in Ambridge, Pennsylvania here is what they found. A bus driver named William McCartney warns the kids that he will “gonna knock you down. I mean I'll knock you down". He threatens the kid twice, while slamming on the brakes hard and kids go flying. These were elementary children and one of them called the bus driver a name. Being a bus driver is a hard job for anyone. William was maybe having a bad day. I’m not defending the guy but he should not have done that. Kids should feel safe even while misbehaving. Hitting the kid does nothing. Do we really want to teach children violence is ok? Even if the bus driver was just treating them. Children don’t learn respect from being hit. Its fear. He was the adult and should have been the adult. The article never said anything about him knowing the camera was there or not but if he did then it is worse cause who knows what he would’ve done without a camera on.
