Corporal Punishment is the practice of physical punishment for bad behavior, and in 2012 the practice in the Western World is pretty rare. I went to public school in South Carolina (with no paper laws prohibiting it) from kindergarten all the way up to my high school graduation in 2006, and I was never hit by a teacher either by hand nor ruler. But now a school in Springtown, Texas has come under criticism when two teenage girls came home with bruises after they were beaten by two male assistant principals.
Punishments in school should never been physical punishment, and I personally believe it should be prohibited in both the public and private schools. Lets say I go down to the this school to attend a football game or special event, and I make a rude comment to one of the teachers or staff. Does that give them a right to physically harm me? No because if they do, that would be assault which is a serious crime. Where down the line does the student lose all their rights in a supposed "free" nation?
The real issue in punishment is moderation. One of excuses corporal punishment supporters have hidden behind is the fact that there are a lot of kids who go unpunished by their parents tend to be rowdy and annoying. However that's because their parents are too weak to punish their child by any means. My brothers were treated far more by physical abuse than I, and after my father died when I was 7 that kind of punishment ended for me. My brothers tend to have far more anger issues than I.
The worse punishment I ever received was in school. I was in middle school drama class and we were doing some kind of skit exercise and got carried away. Our teacher sat us down, brought out 3 copies of the dictionary, and we had to write down definitions verbatim on 3 pages of notebook paper front to back. I never really got punished ever again, except ironically by a high school drama teacher who demanded we bring costumes to the end of the year party (in May) and I told her that Halloween was over for me a few years ago.
To put it simply, rulers are tools of measurement only. They are not weapons, and assault has no place in schools. It is time for all of America to evolve past vengeance and anger and out of all barbaric practices. Teachers should teach, principals should run the school, that is all.
