There were 25 executions in the United States previous year, all carried out by state authorities on people convicted on state charges.
Additionally, while the federal government's previous lethal agent consisted of a drug cocktail, Barr's addendum calls for those sentenced to be injected with exclusively pentobarbital sodium.
Barr approved a new procedure for lethal injections that replaces the three-drug cocktail previously used in federal execution with a single drug, pentobarbital. "Barr has also directed the bureau of prisons to schedule the executions of five death-row inmates", adds Fox. "Because we can't ensure that we get these cases right every time, we must eliminate the death penalty".

"Given the problems that undermine the fairness and reliability of Danny Lee's conviction and death sentence, the government should not move forward with his execution", he said.
The move to execute federal death row inmates was sharply rebuked by opponents of the death penalty.
"Instead, capital punishment seeks to satisfy a desire for vengeance and retribution".
Alfred Bourgeois, who molested and killed his two-year-old daughter.
But that lapse is no surprise as executions in federal prisons are extremely rare.
The most recent federal execution occurred in 2003, when Louis Jones was executed for the 1995 kidnapping, rape and murder of a female soldier.
That's slowed the pace of executions in the 25 states where executions are still legal and able to take place, and it "complicated and prevented" executions at the federal level, a department official said.
