Solid article in the Wall Street Journal today about a prosecutor in Dallas. Craig Watkins was elected DA there in 2006. He's made a name for himself by thoroughly reviewing dubious convictions and using DNA evidence for that purpose.
He actually created a unit within his office, the "Conviction Integrity Unit," to review cases. They've cleared six innocent men so far. Some of the article includes criticism of Watkins by other prosecutors.
I suppose this is no shock to anyone who reads my blog, but I think Craig Watkins is a model prosecutor. This is what every DA should do. I've seen plenty of cases where prosecutors won't back off of crappy cases. They ought to read what this guy is doing.
