The judge didn't order him institutionalized though, he was put on out-patient because he didn't deem him to be a threat.

And that's the key difference that made it okay for him to buy guns.

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.

I haven't heard anything to suggest that what the pawnshop did was illegal, though... it should have been (I fully support gun control -- hunting weapons should be legal, and nothing else), but it wasn't...
