YouTube - Guns And Idiots
Keep your finger off the trigger until your sights are on the target:
YouTube - Shotgun accident
YouTube - accidental shooting
Don't point the muzzle at anything you aren't willing to destroy:
YouTube - Idiot shoots himself with a flare gun
Know your target and what is beyond it. (Also what it is likely to do when hit):
YouTube - 50 caliber sniper rifle rebound!!!

YouTube - Two Idiots With Guns
Most importantly: Get a good carry belt.
