I feel that that any injury sustained by a customer in any establishment that could be perceived by an average person to preventable be on the owner of that business. these injuries should be treated no different than any "slip and fall" injury or "coffee burn" where we see countless times where the victim is awarded millions of dollars. The owner of the establishment, using perverted reasoning chose to create a condition that that puts its customers at risk of an otherwise preventable injury, just like leaving the banana peel on the floor in the produce isle for an extended time these GFZ signs are no different. by placing these signs it must be understood that the ones placing these signs assumes all responsibilities for your safety and welfare and liable for any injury.
Our gun advocacy groups should be sending letters to the owners / board of directors of businesses, malls owners or any other private property owners who make a corporate decision to post signage dictating constitutionally protected personal behavior within their publicly accessible property demanding the name and account of their insurance company and the level of liability insurance should any possibly preventable injury occur to any of it's members.
