Actually, what I remember from my Catholic School days is the teacher would often punish the whole class if one class clown acted out. It made the whole class invested in making the class clown behave.
There's no good reason why civilians should have guns. NONE. Whatsovever. They are more dangerous to family members than bad guys, and you aren't going to overthrow the government with them.
That said, if you really, really need to compensate for your... ahem.. shortcomings, that's fine. As long as you pass a THOROUGH background check, I'm fine with it.
I just had to submit 200 pages of documentation to the government and pay $4000 to update my wife's immigration status from a work visa to a marriage Visa, because people like you are terrified a Mexican might move in next door.
I think I'm entitled to some assurances that you aren't a fucking crazy person before you buy a gun.
