[Harry Potter] How are Hogwarts students kept from going postal?

Every single student is carrying the ultimate multitool: The wand. It is also the universal weapon, and anyone motivated and creative enough could kill and maim their fellow student with the use of ordinary spells, no Unforgivable Curses needed. How do Hogwarts stop the kids from going postal on each other in fits of rage or heartbreak or depression or a thousand other moments of emotional instability that are much too common with teenagers?

Well, literally every other student *also* has a wand. As do all the teachers. And Hogwarts has a hospital wing with basically miraculous medical care available 24/7. So unless you *do* outright kill someone, whatever happens is probably reversible. 

Heck, they can regrow all your arm bones in a single night. So unless you're maiming them worse than *that*, it's not even enough to get the kid out of class the next day. 

And any spell that does *real* damage also requires a lot of *real* power. The younger kids haven't grown into that yet, and the older ones typically learn a thing or two about responsibility in the intervening years. After all, a single bad mistake at Hogwarts can be grounds for you *never* becoming a proper wizard. They could snap your wand and that's that. 

Now, that's not to say kids won't be kids. But typically, they'll be using simpler hexes or jinxes. Distracting, potentially hilarious, but usually not *dangerous*, and certainly not life-threatening.
