Scot-Free Watch, from the Rocky Mountain News: "Federal prosecutors have declined to press charges of impersonating a Secret Service agent against a White House volunteer who forcibly ousted three people from a speech by President George W. Bush in Denver on March 21. The announcement was made without explanation Friday in a letter from the Secret Service to Colorado Sen. Ken Salazar and Reps. Mark Udall and Diana DeGette, all Democrats who had asked for the agency to investigate the incident."
