if you poke around on the web, you will find that such data and questions were used in many anti-gun agenda driven studies that have since run their course. That is, they published their conclusion, then invented the data to support it, it gained traction with the antis, was well refuted by subsequent studies and has since fallen out of favor, but still shows up in the moonbat community and/or in various states dumb enough to jerk their knees to writing laws requiring such crap...I know for certain this was the practice at Boston Medical Center. During my physicals when I was a teenager the medical assistant would ask if I carried a knife and/or gun.I know that it was noted that I carry a knife but have no idea what they did with that information. I have worked as an Ophthalmic Technician and sometimes we would flag patients files if they were problematic. But usually these would be things like male technicians only or let MD put in eye drops. I have seen flags for the occasional pervert but nothing about this person carries a knife or is a gun owner.
There still appear to be antis in the AMA pushing this nonsense, but it seems to be losing steam with the Demunists shooting for a "gun friendly stance" in upcoming elections... (don't believe them, its a bit like the Brown Shirts running on a "diversity" platform).
