Long piece from Foreign Policy about the FBI’s attempted infiltration of the “Patriot Movement” during the 90s:
Despite the fact that PATCON was set up as an intelligence-gathering operation, no evidence has emerged to date that information from the operation came into play during the bombing investigation, despite the links between some of McVeigh’s contacts and the organizations targeted.
The dilemmas of PATCON point toward current debates over the use of infiltration, particularly in cases such as the NYPD’s monitoring of Muslim communities in New York, investigations predicated on the need to collect intelligence rather than build prosecutions on specific criminal activities. The value of the intelligence collected by PATCON is unclear in the final analysis. The only PATCON targets ever prosecuted were already under investigation by the Army, and none of the specific terrorist plots alleged in the FBI’s records ever came to fruition. Meanwhile, the perpetrator of the worst act of right-wing violence in U.S. history was in contact with several targets of the FBI’s investigation but apparently flew under the radar.
