Who Watches the Watchman?

This is sort of fun. David Corn and Jeff Goldberg are on to something intriguing about Mark Felt in the latest issue of The Nation:

According to originally confidential FBI documents--some written by Felt--that were obtained by The Nation from the FBI's archives, Felt played another heretofore unknown part in the Watergate tale: He was, at heated moments during the scandal, in charge of finding the source of Woodward and Bernstein's Watergate scoops. In a twist worthy of le Carré, Deep Throat was assigned the mission of unearthing--and stopping--Deep Throat.

This placed Felt, who as the FBI's associate director oversaw the bureau's Watergate probe, in an unusual position. He was essentially in charge of investigating himself. From this vantage point Felt, who had developed espionage skills running FBI counterintelligence operations against German spies in World War II, was able to watch his own back and protect his ability to guide the two reporters whose exposés would help topple the President he served.

Somebody ought to make a movie about this.
