Don't worry your pretty little heads about yet another classified top secret federal police program

The recent disclosures of agency activities by its former contractor Edward J. Snowden have led to widespread criticism that its surveillance operations go too far and have prompted lawmakers in Washington to talk of reining them in. But out of public view, the intelligence community has been agitated in recent years for the opposite reason: frustrated officials outside the security agency say the spy tools are not used widely enough.

“It’s a very common complaint about N.S.A.,” said Timothy H. Edgar, a former senior intelligence official at the White House and at the office of the director of national intelligence. “They collect all this information, but it’s difficult for the other agencies to get access to what they want.”

“The other agencies feel they should be bigger players,” said Mr. Edgar, who heard many of the disputes before leaving government this year to become a visiting fellow at Brown University. “They view the N.S.A. — incorrectly, I think — as this big pot of data that they could go get if they were just able to pry it out of them.”

A secretive U.S. Drug Enforcement Administration unit is funneling information from intelligence intercepts, wiretaps, informants and a massive database of telephone records to authorities across the nation to help them launch criminal investigations of Americans.

Although these cases rarely involve national security issues, documents reviewed by Reuters show that law enforcement agents have been directed to conceal how such investigations truly begin - not only from defense lawyers but also sometimes from prosecutors and judges.

The undated documents show that federal agents are trained to "recreate" the investigative trail to effectively cover up where the information originated, a practice that some experts say violates a defendant's Constitutional right to a fair trial. If defendants don't know how an investigation began, they cannot know to ask to review potential sources of exculpatory evidence - information that could reveal entrapment, mistakes or biased witnesses.

"I have never heard of anything like this at all," said Nancy Gertner, a Harvard Law School professor who served as a federal judge from 1994 to 2011. Gertner and other legal experts said the program sounds more troubling than recent disclosures that the National Security Agency has been collecting domestic phone records. The NSA effort is geared toward stopping terrorists; the DEA program targets common criminals, primarily drug dealers.

"It is one thing to create special rules for national security," Gertner said. "Ordinary crime is entirely different. It sounds like they are phonying up investigations."

The unit of the DEA that distributes the information is called the Special Operations Division, or SOD. Two dozen partner agencies comprise the unit, including the FBI, CIA, NSA, Internal Revenue Service and the Department of Homeland Security. It was created in 1994 to combat Latin American drug cartels and has grown from several dozen employees to several hundred.

Today, much of the SOD's work is classified, and officials asked that its precise location in Virginia not be revealed. The documents reviewed by Reuters are marked "Law Enforcement Sensitive," a government categorization that is meant to keep them confidential.

"Remember that the utilization of SOD cannot be revealed or discussed in any investigative function," a document presented to agents reads. The document specifically directs agents to omit the SOD's involvement from investigative reports, affidavits, discussions with prosecutors and courtroom testimony. Agents are instructed to then use "normal investigative techniques to recreate the information provided by SOD."

A spokesman with the Department of Justice, which oversees the DEA, declined to comment.
