The execution chamber at the Utah State Prison after Ronnie Lee Gardner was executed by firing squad in Draper, Utah, in 2010 for aggravated murder. Four bullet holes are visible in the wood panel behind the chair.
South Carolina's Republican governor signed a bill into law last week that sounds like it's from a different century: death row inmates must choose whether to be executed by the electric chair or a firing squad, if lethal injection drugs are unavailable.
Lethal injection is the preferred method of execution in states that have the death penalty. But in recent years they've have had difficulty obtaining lethal injection drugs, as pharmaceutical companies blocked their drugs from being used in executions.
