When my nephews visit, I always lock up my firearms. (They are 21 and 22 but have no real firearm training). That said, that’s my choice. Some idiot school board trying to make me do so? My answer would be NUTS (ref General McAulliffe in WWII).
I do the same when the neighbor kids come over. Otherwise, my house, my locations for placement. As usual situational awareness counts.
(ref General McAulliffe in WWII). Yeah, I’m old enough. LOL!
If someone thinks their child or guest is a bit unstable, they should store their guns with a close neighbor, and have that neighbor on speed-dial. In case the neighbor might be slow, arm yourselves with blades or something. And never tell snoopers anything.
