Justice Scalia says it is ok to execute an innocent person

Per Justice Scalia there is nothing unconstitutional about executing an innocence person.

"The Georgia Supreme Court rejected petitioner’s “actual-innocence” claim on the merits, denying his extraor-dinary motion for a new trial. Davis can obtain relief only if that determination was contrary to, or an unreasonable application of, “clearly established Federal law, as determined by the Supreme Court of the United States.” It most assuredly was not. This Court has never held that the Constitution forbids the execution of a convicted defendant who has had a full and fair trial but is later able to convince a habeas court that he is “actually” innocent. Quite to the contrary, we have repeatedly left that question unresolved, while expressing considerable doubt that any claim based on alleged “actual innocence” is constitutionally cognizable."
