As an LEO, there is a couple hundred ways for an LEO to misinterpret your intentions. One example is during the course of the traffic stop, your handgun starts to fall on the floor. You make a quick move to grab it, and the next thing you know you were standing at the pearly gates. I have not, so far at least, ever run across a CCW holder that I was particularly worried about, but that does not mean every person who has a CCW is Pro Police. In fact it may be very much the opposite. Don't assume every LEO is going to run a check on you every time. He may have just received a priority call and he has to run.... and he walks back up to see a gun some where you thought he could not see it. I don't like surprises. and yes we have arrested more than a couple knuckle heads who were armed and did not tell us. I would think you would want to say it first thing just in case you had a little brain lapse and thought you left your handgun at home and but had it all along. Saying it does not hurt anything. Its just good insurance. (Nobody out there who ever left their wallet at home or locked their keys in their car??) Remember LEO's have families and house payments and all that,.... and we want to see the sun come up tomorrow just like you do. Lastly, I really don't care if someone is offended, My duty is to stay alive and keep myself safe so I can protect others. I will continue to do that the best way I know how.
