The FBI has been run by liberal Washington lawyers since the 1990s, some of whom pretend to be Republican. They will never go after Antifa or BLM because they serve the political agendas of the Democrats. They aren't even allowed to admit antifa exists as an organized group. There aren't any bill boards of wanted leftist rioters going up anytime unless police departments put them up. Fat chance of that happening either in democrat-controlled jurisdictions.
