Patrick Gray, I understand from the usual liberal sources, was a political hack appointed by Nixon as FBI director. His resume did not include professional work with the FBI, CIA, or any other security organization. He had every reason to protect Nixon and his associates.

I suppose Felt could have brought his concerns to Gray, if he'd been incredibly naive. I don't really find what Felt did "strange," just incredibly brave. Apparently Woodward had gained his confidence as a friend previously over a number of years, after a chance meeting at the White House when he was a Navy courier.

Cheerily,
