I realize this thread is a little old, but since it hasn't been locked down, I wanted to mention something that reading all the above brings to mind.
First off, I don't care one way or the other about informing during a stop. If it helps the officer, fine. Happy to let them know.
What I don't understand is, aren't these officers approaching ALL stops considering a worse case scenario? How would somebody licensed and not informing them of it, make things more dangerous for the officer?
I can understand that by informing them of a license and gun would tend to be a reassuring thing, but can't agree with the notion of not informing as being so much more dangerous, to the point of being illegal and possibly worse.
I would approach all stops with the mindset that things could go south.
If they were up front and told me of the gun and permit? Thanks for your intent, but my mindset would remain the same.
I will disregard the abuse cases of doing either because I think they are the exception.
