But Actually ...
Despite the forward march of execution technology, it's only been about four years since the last firing squad execution was carried out in America.
In Utah, those sentenced to the death penalty had their choice of execution method from a list of options (you can't choose "be kicked into a jet engine by Steven Seagal"). This tradition technically ended in 2004, when the firing squad was officially outlawed in favor of lethal injection as the go-to technique for reducing the population of death row, but a caveat in the rule stated that anyone who received a death sentence before then was still permitted to choose to go out in a hail of gunfire.
It just has a certain flair to it, on top of giving you a good setup for your last words.
Double murderer Ronnie Lee Gardner, who was sentenced to death for murdering a lawyer while trying to escape trial for a previous murder, was the only guy since that ruling to decide that being shot to death was somehow better than dying peacefully in his sleep. And so, after sitting on death row for 25 years, Gardner was strapped to a chair and had a target painted over his heart, and five officers who volunteered to be a part of history were equipped with old school .30 caliber Winchesters. In line with tradition, one was loaded with blanks so that none of them could feel guilty (or on the other hand, brag) about being the one who fired the kill shot.
