I have encountered a number of police officers since I started OC'ing on a regular basis three years ago, the last being eight days ago; the sheriff of the county in which I live. And I have also had encounters will CC'ing as well.. of an interesting variety. Some of the encounters have been almost comical and none have been negative in any way.
A few years ago, I went into Micro Center in Fairfax to get a flash drive they had advertised. While I was trying to find it, I caught some movement out of my peripheral right (strong) side. I casually turned my head slightly to see someone in uniform standing right next to me, as in approximately two feet away. At first, because he was so close, I thought he was a rent-a-cop but a little more turning of the head proved that not to be the case. He was a Fairfax LEO. He sorta hung around me and we both even hit the register around the same time where he asked me if I had found what I was looking for (we had exchange a few niceties when we were trying to find our sought-after items).
I keep wondering when the time will come when I get into a confrontation or semi-altercation with an LEO, but it has just not happened yet.
