The state prepares to execute a man -- over the objections of one of the prosecuting attorneys -- because being black makes him more dangerous. No seriously:

A Texas inmate sentenced to death--in a racially charged case that now-Sen. John Cornyn (R-Texas) said was inappropriately decided--has petitioned Gov. Rick Perry and his state parole board for clemency, giving the GOP presidential candidate two days to decide whether to commute the sentence or grant a temporary stay of execution. Last week, one of the Harris County prosecutors who helped secure Buck's conviction wrote a letter to Perry urging him to grant a retrial. In 10 years as governor, Perry has presided over 234 executions, more than any other governor in modern history; only once has he granted clemency in a case where the Supreme Court hasn't already mandated it. Now, just as he steps onto the national stage, Perry will have to make what looks like a tough call--with GOP primary voters watching. The inmate, Duane Edward Buck, is set to be executed by lethal injection on September 15 for murdering two people at the home of his ex-girlfriend in 1995. 

The issue at hand isn't Buck's innocence, but the means by which his death sentence was obtained. Prosecutors firmly established Buck's guilt, but to secure a capital punishment conviction in Texas they needed to prove "future dangerousness"--that is, provide compelling evidence that Buck posed a serious threat to society if he were ever to walk free. They did so in part with the testimony of a psychologist, Dr. Walter Quijano, who testified that Buck's race (he's African American) made him more likely to commit crimes in the future. (Quijano answered in the affirmative to the question of whether "the race factor, [being] black, increases the future dangerousness for various complicated reasons.")
