AndThen?
pull the trigger.
last i checked, people kill people. if someone gets mad enough, they will find a way, knife, bat, car, piano wire, 2X4, even their own bare hands.
a gun will not fire on it's own unless misshandled or tampered with. if you load a pistol, pull the hammer back, and set it on a table, it will not fire. the chances of that gun fireing is slim to none (unless like an earthquake happens with a hair trigger, even then small chance). there's a better chance of the gun powder going bad.
No one's going into Virginia Tech and killing 32 people with their bare hands, though.
