#1 - the Barnes & Noble bookstore in question does not have any manner of "no guns" policy posted. The police officers asked if I was welcome in the store any longer, and they said "sure, no problem" - it wasn't the management who called, it was a single patron.
#2 - I was not asked to leave by the store management, even indirectly. Once it was returned to me by the officers who had confiscated it, I reloaded my firearm, concealed it, and went back into the store and purchased $200 worth of DVDs and books with my wife.
#3 - if 99% of the patrons were alarmed, don't you think there would have been more than one 911 call?
Hope you, at least, get an apology. I wouldn't lay even money on it though.
Why don't you e-mail Barnes and Noble, ask what their position is on customers entering their stores with open, loaded weapons. My guess, they are against it, and so is the insurance company that writes their policy. Hey wait a minute, I'm going out on a limb here, but I'm going to guess they don't want any loaded weapons on their premisis , concealed or not!
