An undercover agent in the
Klu Klux Klan reported two murder plots
to the FBI.
He also reported on uniformed "law enforcement" officers who were
traitors, working for the KKK. The agencies they worked for were
ineffectual at controlling this. Look at the Florida agency which
asks us to suppose that this problem is entirely a thing of the past.
The FBI has history of catching fantasy terrorists that could never
have committed violence in the real world without FBI informants'
holding their hands.
They were caught with fake explosives that they
believed were real.
In this instance, the FBI investigated people who could have really
carried out violence, or helped do so. The FBI was really doing its
job.
The fantasy terrorists were Islamists. It does not appear there is
a real Islamist terror network in the US,
but there is a real
white-supremacist terror network
