Threadshitting is still bannable, correct?
ThinkProgress has been known to take a very myopic stance on criminal justice that ignores such minor details as "What did the accused do?" And "Is he or she guilty?"
And considering that we have somebody on the first page calling for the President to commute the guy's sentence (despite knowing nothing of the evidence used to support a guilty verdict, as well ignoring the fact that the guy wasn't convicted of a federal crime), you could argue that this article which doesn't contain much actual information is written to elicit a certain reaction.
By the way, the legal question here doesn't seem to be about whether Buck brutally murdered two people and injured his own sister (he did) but about whether he should be sentenced to death.
ETA: Just going off of Wikipedia, because it's late, apparently the other 5 defendants the racist asshole's testimony was used for were re-sentenced to death, because apparently the prosecution had enough supporting evidence besides the asshole's testimony to secure that sentence. You could argue that this is Texas, which is sadly fairly liberal with its use of the death penalty, but you have to leave open the possibility that (if true) prosecutors still had enough to back up a death penalty besides some racist hack. (The footnote leads to a dead Huffpost link, so I can't confirm.)
