Nicholas Kristof in the New York Times:
President Trump is now calling for expanding the death penalty so it would apply to drug dealers and those who kill police officers, with an expedited trial and quick execution. A majority of Americans (56 percent, according to Gallup) favor capital punishment, believing that it will deter offenders or save money and presuming that it will apply only to the vilest criminals and that mistakes are not a serious risk.
All these assumptions are wrong.
My interest in the death penalty arises partly from a mistake of my own. At the beginning of 2000, I spoke to Barry Scheck of the Innocence Project, who told me about a white man on death row in Texas, Cameron Todd Willingham, whom he believed to be innocent. I discussed with editors the possibility of doing a deep dive into the case but let myself be lured away by the sirens of that year’s Iowa caucuses instead. I never wrote about Willingham, and he was executed in 2004.
Subsequent evidence strongly suggests that not only was Willingham innocent but that no crime was even committed.
