Alabama inmate James Barber is scheduled to be put to death Thursday night, in the first execution scheduled in the state after a months-long pause following a series of botched executions nationwide and increased scrutiny over the use of lethal injection — the most widely used death penalty method in the country.

Several states have faced various problems with the execution method, including in Alabama and Arizona, where executions have been called off because of difficulties inserting IVs into veins, issues with the lethal chemicals or needles becoming disengaged. 

Since Texas became the first state to use lethal injection in 1982, U.S. states and the federal government have put about 1572 prisoners to death “by some version of the method,” according to the Death Penalty Information Center. 

Although proponents have endorsed the method as a painless and more humane way to carry out executions, some experts have said lethal injection is the most botched of execution methods. 

Capital punishment has also been in decline nationwide since at least the beginning of the 21st century, according to a February analysis from Eastern Kentucky University. 

“For the eighth consecutive year, fewer than 30 people were executed and fewer than 50 people were sentenced to death,” the Death Penalty Information Center said in its 2022 report. “… The five-year average of executions, 18.6 per year, is the lowest in more than 30 years, a 74% decline over the course of one decade.”
