I don’t think the deep state will give up their police state operatives. The FBI cannot be reformed by government criminal bureaucrats.
The people must act at the grass roots to make the FBI a detested and disrespected organization. Even if it means that in court cases where the FBI presents credible evidence, it is rejected and a guilty party goes free. Juries must invoke nulification during trials. The public in general should stop giving the FBI evidence - give evidence to state and local law enforcement. These Feds do not deserve our respect in public life. Sorry to those who are doing good work, but your agency is too corrupt to fix; it has to be completely purged and rebuilt as a smaller agency.
So, what should people do when they see a crime, report it to state and local officials. We should also encourage states not to refer cases to Federal agencies unless there is an absolute necessity (as when a case is multi state or international).
Today, with the internet, there really is no longer a need for a centralized criminal investigative agency. If fact, based on the perversions of the FBI, the dangers of centralization outweigh the benefits.
