In a brief video published to YouTube, television judge Greg Mathis, who formerly served on the bench in Michigan, clearly laid out his thoughts on the execution of Georgia inmate Troy Davis.

"I don't like to contradict other judges, but Davis should have been grated a new trial so that he could prove his innocence," he said. "This was, without a doubt, a grave miscarriage of justice. We've long known our system of justice is broken. Davis's execution shows us just how broken the system has become."

Mathis concluded: "We need a nation-wide ban on the death penalty. One innocent man put to death is one too many. If we can't be certain of the legitimacy of the convictions, the practice must be halted. It is criminal that this man was executed with so much doubt surrounding his case, and Georgia has blood on its hands."
