I guess I'm also in the minority here.
If I'm carrying, I wouldn't inform a LEO since my home state (PA) doesn't require me to. And, contrary to popular belief, I'm not required to give him a yes/no answer to the question "Do you have any weapons on you?" I can stay silent or answer with a question "What's the problem, officer?".
Only if he has reasonable suspicion that you have a firearm can he require the LTCF.
In my opinion, my right to travel and live freely trumps the officer's rights to restrict them. He should have PC before going on fishing expeditions. Plus, if I inform him that I am indeed carrying, there's a fair chance of him going into panic mode and thinking I'm going to draw and unload on him. In the end, since that would almost never be my intention, it would be safer to just not bring it up if you aren't required to.
Then again, I'm big on the exercise of rights and the restriction of government from intruding on the personal lives of those it governs. Each one of us has to figure out for ourselves how far we are willing to let government in on our lives.
