Cops keep coming up on my porch. I keep answering the door with my gun strapped to my hip. The cops with say nothing, or say something fun and cool.
Today a cop stopped by passing out a notice to watch out for burglary. I thought it was the mailman and opened the door, and he turned around to chat for a minute. At the end he says "just be careful and lock your doors" so I angle my hip in his direction and say "We're good here man." He notices the gun, smiles, and says "yeah, I guess you're good here!" and we tell each other to have a good day and that's the end of it.
It's cool being the local gun nut/"neighborhood watch"... actually much more fun than I imagined! :)
