The Herald-Sun, quoting a deposition given by investigator Linwood Wilson, says Wilson advised Durham DA Mike Nifong more than a year ago to administer a polygraph test to accuser Crystal Gail Mangum:

In his deposition for the N.C. State Bar, Wilson quoted Nifong as saying, “I don’t polygraph victims, especially sexual assault victims … and make those victims think that I don’t trust them or believe them.”

I imagine that NIfong rues the heck out of that decision right now.
