Trained professionals reduce error rates in executions by firing squad, the lawsuit claims.
"The firing squad significantly reduces a substantial risk of unnecessary and severe pain when compared with" Tennessee's three-drug cocktail used in lethal injections, sparing the men suffocation, internal chemical burn and paralysis, The Tennessean reported, citing the lawsuit.
Only Mississippi, Oklahoma and Utah formally authorize the use of a firing squad, according to the Death Penalty Information Center. It was last used in the United States in 2010 by Utah officials.
