When our oldest daughter took her 1st child in (about four years ago) the Pediatrician asked the gun question. Our daughter was somewhat taken aback but told the truth and said no.
However, it's a good thing the Doc didn't ask about Samurai Swords, 'Ninja' and assorted edged weapons, as our S-I-L has a boat load of those. To paraphrase Beatrix Kiddo (the Bride) in Kill Bill Vol 2,
"He is proficient in the exquisite art of the Samurai Sword."
Needless to say we get along just fine. No wussies for my daughters :-)
THIS rather puts the lie to it in a nutshell.
People are much more likely to be cut or stabbed, than shot; EVERY household has them; and, typically, knives (steak, kitchen, pocket, etc) are treated & secured in a much more blase fashion than guns.
It isn't "only about safety"; nor does the answer, if any, warrent being recored in the patient record.
