Citizens Business Bank gets an "F" for citizenship. A people trained to arms and bearing daily would recognize the evil in restricting invitees from lawful carry. Such a business would never defend its customers from violence, and more than that, the restriction frustrates daily carry and possibly results in unsafe weapon handling in the parking lot as customers unload and lock up their weapons. Rights do not exist in a vacuum and property rights of the business do not trump the right to life and other liberty and property rights of the invitee.
I have to walk by this offensive sign every day as I pass through the lobby of my office building in Laguna Hills. The sign is misleading in that the entire "building" is not controlled, only the bank's portion of the first floor, and from my observation they are probably not even very effective at that.
