Lawyers for Robert Bowers, accused of shooting in the Pittsburgh Synagogue in October 2018, which claimed the lives of 11 people, consider the possible death sentence of the court to be unconstitutional, the Associated Press reported.

Lawyers said capital punishment violates the Fifth Amendment’s due process clause and the Eight Amendment’s ban on cruel and unusual punishment.

"They also said the practice of carrying out federal executions in state prisons violates a Tenth Amendment protection that says states can’t be made to enforce federal laws, the Pittsburgh Tribune-Review reported Friday," the source said. "Defense lawyer Judy Clarke has made similar arguments in other high-profile capital cases. Her clients have included Boston Marathon bomber Dzhokhar Tsarnaev, who is appealing his 2015 death sentence, and Unabomber Ted Kaczynski, who entered a plea agreement that spared him the death penalty."

In her complaint, Clarke claimed  that she had tried to negotiate a life-in-prison sentence , but has been rejected
