RD's post makes the most sense to me so far.
I happen to spend quite some time waiting in line at Starbucks, the Car Wash, Restaurants, etc. I have never notified a LEO in any of these circumstances and I never will.
Waiting in line with a cop right behind me is not official contact. Sitting on a park bench next to one is not either. No they will not shoot me dead if they see me printing. I am not worried about it, not for one second. They do not and can not know who I am. They also don't know what is printing. Everybody and his brother carries 15 items around their waist these days. I don't. I only carry two: My .45 and my spare mag. My gun prints less than your IPod or Blackberry.
Official contact to me is not a nod with a quick 'how are you'. Being stopped by LE is a no brainer. I will notify. I will notify no mater what state I am in and no matter what the terms of the license. It is a matter of courtesy and officer safety and ultimately my own. It may also help...
The comment of 'its none of their business if I carry' does not cut it for me. It's all about attitude. Act like a professional and be treated as such. Act like a **** and get you butt kicked. End of rant.
