Came across this article from the LA Times: http://latimesblogs.latimes.com/outposts/2010/02/hunter-shot-by-his-dog.html
Earlier in my career as a paramedic, I've treated injuries that were the direct result of carelessness with a firearm. One case that stands out was a bird hunter that had leaned his shotgun up against a tree and walked away from it. Well he didn't have the saftey on and it fell over and went off. The gentleman ended up with a chest and face full of #6 shot. He survived but lost an eye.
We're taught in hunter safety classes about the importance safe firearm handling. Perhaps these hunters were not paying attention during that part of the class. Personally, I leave my safety on until a second before I pull the trigger.
Treat every firearm as if it is loaded
Always keep the muzzle pointed away from you.
Be sure your firearm is in good working condition.
Be aware of what's beyond your target/decoys.
KEEP YOUR SAFETY ON!!!
Alcohol/drugs and firearms don't mix.
