Wild Bill fatally shot his deputy with a single action revolver. That's documented.
But he did it "on purpose", mistaking him for an assailant running up behind him. Not an accidental S.A. shooting, but incorrect target identification.
Sometimes you get what you pay for, sometimes you only pay more for what you get.
Three shots are not a "group"...they are a "few".
If the Bible is the literal, infallible, unerring word of God...where are all those witches I am supposed to kill?
