DEA Presentation Shows How Agency Hides Investigative Methods From Trial Review

v3rgEz writes "CJ Ciaramella stumbled upon some interesting documents with a recent FOIA request: The DEA's training materials regarding parallel construction, the practice of reverse engineering the evidence chain to keep how the government actually knows something happened away from prosecutors, the defense, and the public. 'Americans don't like it,' the materials note, when the government relies heavily on classified sources, so agents are encouraged to find ways to get the same information through tactics like 'routine' traffic stops that coincidentally find the information agents are after. Public blowback, along with greater criminal awareness, are cited among the reasons for keeping the actual methodologies beyond the reach of even the prosecutors working with the DEA on the cases."
