If an Agent Knocks

This booklet has been around for awhile, but I hadn't seen it, and found
it informative.

The Center for Constitutional Rights created If an Agent Knocks to
provide advice to activists likely to be targeted by FBI agents or other
federal investigators. Since its original release in 1989, If an Agent
Knocks has been widely circulated in progressive activist communities
across the country.
