JUSTICE: Assistant U.S. Attorney exposed as online troll behind abusive comments about local officials and businessman. “Jan Mann, who was First Assistant U.S. Attorney in New Orleans, doled out personal abuse and even offered opinions on cases she was working on, all under a ‘sock puppet’ pseudonym. This is the second time this year that someone in the office of U.S. Attorney Jim Letten has been caught trolling online, and could endanger the senior prosecutor’s position.” She looks like a troll. And I have to say, “professionalism” sure is taking a beating these days.
