Witness for the prosecution

The always excellent Radley Balko gets yet more mileage from his expose of Dr. Steven Hayne, a pathologist who seems to run a testimony mill for prosecutors in Mississippi. Hayne's credibility has been questioned by that state's Supreme Court, and he's not eligible for certification by the National Association of Medical Examiners because the 1,500 or so autopsies he claim to perform each year far outstrips the maximum 325 that NAME believes an ME can perform with any degree of competence. Yet he's still in business.
