I predicted this...

[Weltall]

He didn't buy from a gun shop, he bought from a pawn shop. Pawn shops need to be licensed to sell guns, and I'm assuming that license will be revoked following this, but you know pawn shops are. If you have money, and what you want is there, it's yours.

He bought one of the guns at a gun shop, Roanoke Firearms, right here in my town. I passed by it yesterday.

The points aside of his commitment to an institution, no record of it appeared on the background checks the proprietors of Roanoke Firearms undertook. If anyone failed here, it's the state of Virginia for making legal such allowances. Any commitment to a mental institution should appear on a background check and should at the very least be a serious impediment to a firearms purchase.
