The Justice Department Inspector General’s office has determined that the Federal Bureau of Investigation mishandled a Florida terrorism investigation, altered and falsified documents to cover up its mistakes and retaliated against a whistleblower who brought the problems to light.

In one instance, someone altered dates on three F.B.I. forms using correction fluid to conceal an apparent violation of federal wiretap law, according to a draft report of an investigation by the Justice Department inspector general’s office obtained by The New York Times. But investigators were unable to determine who altered the documents.

The agent who first alerted the F.B.I. to problems in the case, a veteran undercover operative named Mike German, was “retaliated against” by his boss, who was angered by the agent’s complaints and stopped using him for prestigious assignments in training new undercover agents, the draft report concluded. . . .

The inspector general’s draft report, dated Nov. 15 and awaiting final review, validated most of Mr. German’s central accusations in the case. But the former agent, who left the bureau last year after he said his career had been derailed by the Florida episode, said he felt more disappointment than vindication.

“More than anything else, I’m saddened by all this,” Mr. German said in an interview. “I still love the F.B.I., and I know that there are good, honest, hard-working agents out there trying to do the right thing, and this hurts all of them.”

Mr. German’s case dates to 2002, when the F.B.I. division in Tampa opened a terror investigation into a lead that laundered proceeds, possibly connected to a drug outfit, might be used to finance terrorists overseas. The F.B.I. was considering initiating an undercover operation to follow the lead, and Mr. German, who had extensive experience infiltrating militias, skinheads and other groups, was asked to take part.

But in the coming months, Mr. German would alert F.B.I. officials that the Orlando agent handling the case had “so seriously mishandled” the investigation that a prime opportunity to expose a terrorist financing plot had been wasted. He said agents had not adequately pursued leads, had failed to document important meetings with informants, and had tolerated violations of rules and federal law on the handling of wiretaps. — New York Times

Congressional hearings are scheduled for January on whether national security whistleblowers such as German are being unjustly retaliated against.

It’s a shame when government seems to care more about covering up their mistakes than about doing their jobs.
