Overtones: Death by firing squad is often regarded as a soldier's death rather than a criminal's death, and therefore more noble. It is also the only modern form of execution that preserves most of the prisoner's organs, allowing for organ donation.
How It Works: Firing squad executions are so incredibly rare in the United States that it is difficult to speak of a standard operating procedure, but historically the victim is strapped to a chair, five sharpshooters aim at the victim's heart, and all five pull the trigger. One of the sharpshooters is secretly armed with a blank round, which means that each shooter can rest comfortably in the knowledge that there is a 20% chance that she never shot the prisoner.
Complications: Although both modern firing squad executions went smoothly, it was not unheard of in the past for all five rounds to penetrate the prisoner without killing him--requiring a sixth shooter to fire a round at close range to put the prisoner out of his misery.
