For more on this Georgia case, see Amnesty International. Davis was convicted of killing a police officer at a Burger King based entirely on witness testimonies. There was no physical evidence and no weapon found. All but two of the non-police witnesses have recanted or changed their "recollections" since the trial.
But Davis is up against two big problems:
Now there's a guy with an incentive to stick to his story.
Davis' other problem is that, in the interest of "steamlining" court proceedings, the "justice" system limits appeals. The Supreme Court isn't saying they think Davis was rightly convicted; they are saying they won't look into the issue in the interests of a smoothly operating system.
Yeah, right -- a smoothly operating conveyor belt to execution for unlucky, poor, black folks...
