It's only legal to hit someone if they're children and you outweigh them by 100 pounds. Otherwise it's assault and battery and charges can be brought against you. As bad as that is, I can't' see giving this privilege to strangers who don't have the child's best interests at heart. Spanking is an activity that should be practiced by consenting adults, no more. Well, maybe with occasional exceptions, adults hitting kids should be taboo. I certainly think there is something seriously wrong with any adult who would be willing to strike someone else's kids. People like that are sick and shouldn't be allowed to teach, and school systems that allow and even condone that activity are sick and shouldn't be allowed to exist.
