I have a few thoughts.
I read the first couple of pages of this topic and then scanned the rest. If I missed something really important, I'm sorry. I understand the desire to discuss this subject with others, but generally don't think an internet forum is a prudent place. I don't think it's a very good idea to post what or if you carry in so public a place. For anyone interested in the subject of using force in the defense of yourself or loved ones, I would recommend you read On Killing and On Combat by Lt. Col. Dave Grossman. Don't be put off by the titles. They are well written, extremely informative books written by a guy who is both an Army Ranger (retired) and a licensed psychologist. He trains police officers, consults on institutional security issues and serves as a grief counselor. For example he was a grief counselor at the Jonesborough School shooting. In addition he is an expert on post traumatic stress disorder.
I may turn some people off, but I would never recommend a Glock as a daily carry weapon unless you are an officer in a dept. that issues them and have had extensive training in reholstering a Glock safely.
In some states a Concealed Carry License prevents you from open carry. You may be required to ONLY carry concealed. In some circumstances, showing your weapon whether you meant to or not can be construed as aggravated assault. In any case, a CCW permit never makes you the police auxiliary. In order to draw your weapon, you must be in immediate danger of death or serious bodily harm.
I know a number of police officers who serve with honor and are not in the business for their own ego gratification or because they are power hungry.
