From “Rick Perry’s Big Death Penalty Decision”

There have also been several close calls in Texas on Perry’s watch. Last fall, the state freed an innocent man, Anthony Graves, who had spent 12 years on death row, following a lengthy investigation by Texas Monthly. That and other cases led the magazine to call for a moratorium on executions on the state, explaining that “Five times in the past seven years we’ve learned about a person wrongly convicted and taken off death row or a person convicted on bogus forensic science—and executed.”

Perry, for his part, cited the Graves case as evidence that “our system works.”
