It's interesting that you don't mind be harassed by LE. Perhaps you don't feel it is harassment, but that's what I call it when you are involuntarily detained and talked down to... By all means, if that doesn't bother you, let them do it. Volunteer your ID, your firearm for inspection, throw in an open invitation to search your car and your home, and then volunteer to go 'downtown' with them for questioning... if you want. After all, you have nothing to hide, right?!
I'll be the one to say it: don't do anything you don't have to, unless you want to start walking down the slippery slope I outlined above. When we allow abuse of power because it's only a 'minor inconvenience' we're setting the bar that much higher. In 10 years, the 'minor inconvenience' is taken for granted. Then it gets just a little bit worse.
I am naturally inclined, as most of us are, to take the easiest route. However, I make a conscious effort to lower that bar. I want to leave this world a little better off, not a little worse.
