This is one of those things that I'm kind of "on the fence" about. On the one hand, I get why they do it and I'm all for it, yet while on the other hand, it makes me feel a bit "observed".
While I know my family and myself have nothing to hide, thought of it is a little uncomfortable. That said, do I want the LEO's to not do it? ABSOLUTELY NOT! Like I said, we've got nothing to hide, and my personal mixed feelings pale in comparison to law enforcements ability to apprehend someone who could potentially end up on the wrong side of my Mossberg.
I guess I'm not so much "on the fence" after all.
