If you are an active member of ANY militia group or ANY group that is unhappy with what the government is doing, the most vociferous persons in the group that call for action other than peaceable assemblies and phone and letter writing campaigns ARE INFORMANTS if they aren’t outright government agents.
A friend of mine once told me many decades ago that, in America today if you start a flower-sniffing club with more than three members one of them is an FBI informant.
More than ten members, once of them is an FBI agent.
More than one hundred, the FBI is actually running the organization from leadership positions.
I can remember laughing at this idea. THEN.
