Just an FYI to anyone worried about questions from Docs, very often medical professionals will ask a question not to get that particular answer, but more to see how it is answered. They want to know who do they need to keep an eye on, which kids bruises need a second look, all those things that they are required by law to do, and often asking a question that is "on the list" as it were, to a good doc tells them who they need to be worried about. Simple fact is that despite everyone being safe, lots of kids get shot. Sad but true. So they read that answer, and yeah, I bet they make a call about some folks. I'd bet money that the folks they make a call about, you'd do the same. Their business, maybe, maybe not. When I worked at the oil change shop one of my guys screwed up on calling the cops for a pair that were obviously stoned out of their minds driving with a kid unbuckled in the back seat. Claimed it wasn't our business. Me, I don't care who you are, I'm looking out for kids, don't care what you think of it. Be glad that that office knows guns and is asking with a lot more context in mind.
As for running into folks who know knives, its pretty rare. More often they talk big, and I work with outdoor people, folks who will use a rescue knife sometime in their career, and its shockingly common that they only ever think about the bottle opener (why do so many rescue knives also have a top popper?)
