That is exactly why one of the 10 Commandments of gun safety is "Always have your muzzle pointed in a safe direction".

Last spring I have a rifle go off on me when I took off the safety. Ends up I had some powder holding the sear down so as soon as I let off the safety boom!! The rifle was pointed in a safe direction thank god.

Poop happens that's why you should always follow safe gun handling procedures.
