The past few months, the media has been abuzz with the story of FBI translator Sybil Edmunds. Now, there's a second FBI agent who has come forward alleging that the FBI ignored his warnings.

... in early 2002, when [FBI agent Michael] German got word that a group of Americans might be plotting support for an overseas Islamic terrorist group, he proposed to his bosses what he thought was an obvious plan: go undercover and infiltrate the group.

But Mr. German says F.B.I. officials sat on his request, botched the investigation, falsified documents to discredit their own sources, then froze him out and made him a "pariah." He left the bureau in mid-June after 16 years and is now going public for the first time - the latest in a string of F.B.I. whistle-blowers who claim they were retaliated against after voicing concerns about how management problems had impeded terrorism investigations since the Sept. 11 attacks.
