IRS manual detailed DEA's use of hidden intel evidence

(Reuters) - Details of a U.S. Drug Enforcement Administration program that feeds tips to federal agents and then instructs them to alter the investigative trail were published in a manual used by agents of the Internal Revenue Service for two years.

The practice of recreating the investigative trail, highly criticized by former prosecutors and defense lawyers after Reuters reported it this week, is now under review by the Justice Department. Two high-profile Republicans have also raised questions about the procedure.

A 350-word entry in the Internal Revenue Manual instructed agents of the U.S. tax agency to omit any reference to tips supplied by the DEA's Special Operations Division, especially from affidavits, court proceedings or investigative files. The entry was published and posted online in 2005 and 2006, and was removed in early 2007. The IRS is among two dozen arms of the government working with the Special Operations Division, including the Federal Bureau of Investigation, the National Security Agency and the Central Intelligence Agency.
