Officials in Oklahoma and other states are scrambling to figure out a way to kill people.

Concerned over a lack of access to lethal injection drugs, the Oklahoma Legislature passed a bill in late April approving the use of the gas chamber for executions.

This comes on the heels of Utah’s move in March to bring back the firing squad as an alternative to lethal injection, an announcement that spurred another round of debate about executions. While the Denver Post editorial board wrote that the firing squad was “not a solution,” a piece from Bloomberg View titled “Death by firing squad is more humane than lethal injection” circulated widely.
