Absolutely. A normal function of the FBI is to infiltrate politically ascendant groups that aren't controlled by the republicrat lackies of the international financial oligarchy. Members of "dangerous" groups are then enticed to commit violent acts so that the FBI can come down on all the group members with trumped up conspiracy charge. Any Tea Partier who counsels any illegal acts is most likely an FBI plant.
How do you tell who the FBI agent is at the militia meeting?
He's the guy calling for the violent overthrow of the government.
I have no doubt this is what happened to those dumbasses up in Michigan.
