The firing squad

The firing squad is generally composed of several soldiers or peace officers. The method of execution requires all members of the group to fire simultaneously, thus preventing both disruption of the process by a single member and identification of the member who fired the lethal shot. Some official protocols^[1] called for inclusion of one or more blank cartridges randomly distributed among the live ammunition, giving each squad member a chance of not having killed. The condemned is typically blindfolded or hooded, as well as restrained—though in some cases, condemned prisoners have asked to be allowed to face the firing squad without their eyes covered. Executions can be carried out with the condemned either standing or sitting.
Execution by firing squad is distinct from other forms of execution by firearms, such as a single shot from a handgun to the back of the head or neck. However, the single shot (coup de grâce) is sometimes incorporated in a firing squad execution, particularly if the initial volley turns out not to be immediately fatal.http://en.wikipedia.org/wiki/Execution_by_firing_squad
