I just had to show my conceal permit to a police officer
I got home and was spraying some of my squeaks down with WD in the parking lot when I heard PSSSSHHHHHHHHHHHHHHH. I looked around the vehicle and saw a man withdrawing a foot long sharp object from a neighbor's tire. I immediately lit him up with my maglight and asked him what he thought he was doing and he walked away saying, "She F***ed with me!" I took a few steps after but realized if he was waiting around the corner he had gone around, holding his knife or whatever it was, I'd be forced into a shooting situation (I was carrying). So I stopped and called the non emergency police line. They were there pretty quick. Two cars pulled up and asked if I was the caller. I dentified myself and then told them I was armed. They asked where and I showed my conceal holster. They then asked if I had a permit, which I produced along with my ID. With my mag and gun, they asked if I was a security guard.
Wrote some stuff up and that was it as far as I was concerned.
