Drug Enforcement Administration training documents released to MuckRock user C.J. Ciaramella
show how the agency constructs two chains of evidence to hide surveillance programs from defense teams, prosecutors, and a public wary of domestic intelligence practices.
In training materials, the department even encourages a willful ignorance by field agents to minimize the risk of making intelligence practices public.
The DEA practices mirror a common dilemma among domestic law enforcement agencies: Analysts have access to unprecedented streams of classified information that might prove useful to investigators, but entering classified evidence in court risks disclosing those sensitive surveillance methods to the world, which could either end up halting the program due to public outcry or undermining their usefulness through greater awareness.
An undated slide deck
released by the DEA to fleshes out the issue more graphically: When military and intelligence agencies “find Bin Laden's satellite phone and then pin point [sic] his location, they don't have to go to a court to get permission to put a missile up his nose." Law enforcement agencies, on the other hand, “must be able to take our information to court and prove to a jury that our bad guy did the bad things we say he did.”
