Ever the optimist - his mom is totally cool for carrying a .357 magnum wheelgun. She can shoot, too!
I do hope the moron has a full recovery.
Update: SailorCurt has a good point: what kind of moron dons a ski mask and tries to scare his mom with a gun that has a worn off serial number? Said moron is more likely a crack head that botched a real robbery of his mother, and claimed the whole thing was a big joke when mommy dearest put some holes in him. Good catch!
I'll just hang more kudos on the mother for not telling her son she carries a gun. Funny how such a little device can be such a big game changer.
