While it's true that there is a significantly reduced chance of death in school, that is no guarentee of anything. Besides, if they don't kill you they can still break your legs, which could impede your ability to walk indefinately. If someone hits you, from a legal perspective you're perfectly within your rights to hit them back. That doesn't mean that the school won't take action. But all the school can do legally is with-hold services or order a detention. If you win, you could be held responsible for medical bills. But if they swing first, they would likely not be granted. Bottom line, being sued $2,000 dollars for his medical fines is much better than having $2000 in your own medical bills. I go by the policy "If they swing first, I get the last swing." So far I've never had to enforce "the policy".
