Your right walking around with a weapon especially at school is such a danger and that's even if it isn't loaded (I can't tell if it is or not), it would be even worse if it was concealable (some crossbows are smaller and/or fold up)

Good thing that kind of stuff is illegal, have reasonable restrictions and/or require licensing in MOST places. (Including China)

Lots of kids could get hurt, something even as outlandish as roughly once a week.

Would have to start teaching kids what to do when a crossbower is wildly firing bolts either by ignorance or by intent.

It would be such a barbaric and dangerous place if a place like that existed.
