Yes to previous training and some sort of pre-qualification course of fire and stress test.
Education is key. I get people liking their AR but in MY house with other occupants I'm choosing something with much lower energy. Something like a reduced recoil 12ga. Know your target and know what's behind your target... that could be the next 4 or 5 trailers in the trailerhood as Toby Keith would say
Totally agree on education. And while I teach a bunch of AR stuff, me personally that is a lot of gun for our home with occupants. I too go for a less energy choice. In our particular case it is a pump twenty. Let the haters hate!
