The electric chair seems to possess an especially gruesome fascination and has been the subject of many films.

FIRING SQUAD
It is estimated that 340 men have been executed in the U.S. by firing squad since 1600. Many of these were military executions carried out in the civil war. In modern times only Idaho and Utah have allowed execution by firing squad but in practice only Utah has used it since the resumption of executions in 1977.
Nevada carried out one execution by shooting using an "execution machine". This was on May 14th 1913 when Andrija Mircovich was executed for murder. It is however the most common method of execution in use worldwide - 71 countries use shooting as the method of execution, either exclusively or for some classes of crime or criminal.

Utah.
Under Utah law since 1852 the condemned man had the choice of shooting by firing squad (which complies with the Mormon doctrine of Blood Atonement) or hanging, most prisoners choosing shooting. To date, there have been forty-eight legal executions in the state of Utah. Of these, thirty-nine were by firing squad, six by hanging, and two by lethal injection.
On 17 January 1977 Gary Mark Gilmore became the first person to be executed in the U.S. for ten years after putting up a strenuous campaign to be allowed to die. He had been convicted of the murders by shooting of a motel owner and of a gas station attendant. At the time of the killings Gilmore was on parole from a twelve-year sentence for armed robbery.
