Supporters of the bill focused their arguments on efficiency, while some opponents cite a lack of data could bring potential litigation.

On Wednesday, Senate Judiciary and Rules Committee members voted 6-3 to advance HB 37, a bill which would replace lethal injection with death by firing squad as Idaho’s primary execution method for death row inmates. Currently, the firing squad is Idaho’s secondary method.

A bill to make death by firing squad the main method of execution in Idaho is another step closer to becoming law. Under House Bill 37, Idaho would become the only state in the U.S. to have death by firing squad as the primary method of killing those convicted of violent crimes.
