No, its not against the law. No, it doesn't mean he's a nut. Yes, I have my own that I occasionally wear...
But unless you're in the field hunting, doing work around the house, or just cleaning out the the damn stalls, wearing military style clothing while under arms is dangling raw bleeping meat in front of the cops. Come on.
Nothing wrong with that, when I got out I literally wore out the rest of my BDUs they're good work clothes, they were designed to be.Plus the little woman thinks I look sexy in them, hmmm maybe a trip to the surplus store is in order.
