The execution through a firing squad or gunning started taking place as gun began replacing melee weapons. Commonly used in war torn countries or previously a death option in America. Now only two states are only allowed to use it : Idaho and Utah. This method also allows you to donate you're organ. The way a legitimate fire squad method works is, one man is secretly issued a blank, so that nobody knows who fired the killing shot. However, a rifle firing a blank produces less sound than a rifle with a live round. The last excution by firing squad was chosen in Utah, by John Taylor, in 1996, over a lethal injection method.
