No, its not. When that does happen and a couple of cops see it, it opens you up to being contacted, having your CCW permit inspected and if you didn't have one, arrested for illegally concealing a firearm on your person.
We made an assessment of the person and decided to not further investigate. Whether he was a CCW holder or a newbie cop or someone illegally concealing a weapon, I don't know.
As with most things in law enforcement, it is a discretionary action event.
I made an assumption that the person might be here on the forum, given there are a number of people here who list Highlands Ranch as their home and others who live close by from here.
it certainly developed into a topic of discussion for me and my buddy as well as here.
