Question. . . isn't there still a state or two that has firing squad as a legal means of execution?

Utah did.

This from the Mormon church so that a man could have his blood spilled on the earth and atone for his own sins.

Of course, only Christ's blood could ever pay for one's sins.

Mormons believe murder isn't covered by the atonement, neither is adultery.
