Gun Safety Rules

[Ketsuban]

Kromm (as always) makes a lot of sense.

I can't help but wonder, though... given two people who've never held a firearm before, if one of them has received the safety lecture and comprehends the Rules enough to make a valid attempt at being safe even if he can't necessarily recite them from memory doesn't he stand an improved chance of not shooting his own balls off versus the other guy?
