Luckily I'm in a position of authority within the house- The only one that exceeds my authority happens to be buddy, but gun safety doesn't respect rank. I sent out a message to everybody with the following topics:
- The four laws of gun safety
- CF range protocol
- The use of proper eye protection
- The proper storage of guns
- The importance of safety above all else
So far feedback has been good- The rest of the house supports gun safety, and the topic has been added to the agenda for the next house meeting after the break. I plan on refining the email a bit and pushing it as an amendment to the house constitution/by-laws.
Until then though, if he does anything stupid with the gun again, his gun's magazine will conveniently fall into an obscure nook and cranny somewhere in his room.
