FBI's Tactics in Combating Domestic Terrorism Revealed in Recent Documents.

Internal documents obtained by the House Judiciary Committee show that the FBI planned to develop sources inside Christian churches and Catholic dioceses to combat domestic terrorism. The FBI aimed to use churches as "new avenues for tripwire and source development" and specifically target "mainline Catholic parishes." The agency also expressed interest in "leveraging existing sources" and sensitizing religious congregations "to the warning signs of radicalization." The FBI's efforts have been criticized by Republican lawmakers who say they may violate the First Amendment. The committee has issued a subpoena for related documents.
