From the ACLU & Human Rights Watch press release:
Corporal punishment, legal in 20 states, typically takes the form of "paddling," during which an administrator or teacher hits a child repeatedly on the buttocks with a long wooden board. ACLU and Human Rights Watch interviews found that students with disabilities also suffered many other forms of corporal punishment, including beatings, spanking, slapping, pinching, being dragged across the room, and being thrown to the floor.
I am speechless to think that this occurs anywhere in America, with any student. Just speechless.
