Of course, I don't know of anyone who has to show off their smoke detectors to a buddy. And even if you did, the worst that might happen is the thing might make a loud noise. Not so with a gun:
Justin Adkins was hosting a barbecue at his home. Brevard County deputies said Adkins, 25, was showing a friend his .380 caliber when it accidentally fired.
The bullet went through the wall and into the kitchen, striking Kasey Canada in the back.
