In England there is now a new law that teachers can "use reasonable force to restrain violent pupils" but what constitutes "reasonable"?? some parents will still be eager to sue, like; "how dare you touch my child, he/she is sweet natured & lovable", yeah, right, in the past irate parents, mostly the mothers have come to the school & physically attacked the teacher, on one occasion the teacher was knocked to the floor & broke her leg, does this sort of thing hppen in America guys?
