I think citizens could could do more by never reporting, communicating, or cooperating with the FBI for any reason. If asked by a known FBI agent “where is the restroom?” The reply should be I want to speak to my attorney. There is no provision in the Constitution that provides for a federal police force and absolutely no provision for armed federal agents in any capacity. Under our Constitution only the people have the right to bare arms, outside of the military the federal government has no such rights. All police powers should reside with the states.
Or use Hillary's dozens of answers, "I can't recall. I have no memory of that." etc. Don't say, "I don't know", because if evidence proves otherwise, perjury.
