Haha... One would be correct! There is no formal policy that prohibits my carrying. Primarily, I am concerned that it would get back to my company and they would create such a policy. My job is a little different. I am a trainer, and I go out with people to train them, so this is not "carpooling" we are talking about. I also might be with people who work for my company or any company that has a contract with mine. So it's a gray area that I don't want anyone to separate into black and white for me. Beside that, it's my practice not to talk about the fact I am carrying... ever. IMO, the best time for anyone to know I am carrying is about the same time they know I need to be.
As far as informing the LEO when I am not carrying, they find out you have a CHL as soon as they run your license, and the same drill ensues, but I figure if we get it out of the way early, then I don't appear to be keeping anything back. In TX, all the LEO's I have encountered have been very supportive, so I have no reservation. Even if I did, those guys and gals face a lot of unknowns in their world. If I can take one question mark out of their day by saying, "Here's my permit, but I am not carrying." then I am okay with that.
