“If antifa gets to the point where they start killing us, I’m going to kill them next,” Kohfield, 32, said. “I’d slaughter them and I have a detailed plan on how I would wipe out antifa.”

That threat pushed the FBI’s Joint Terrorism Task to take a series of extraordinary steps against Kohfield, including temporary seizure of a cache of his firearms under Oregon’s new “red flag” law aimed at preventing gun violence, The Oregonian/OregonLive has learned…

The moves came as city officials and law enforcement prepared for potentially violent clashes Aug. 17 during a right-wing rally and counterprotests planned in downtown Portland that had become inflamed with incendiary political rhetoric nationwide. Police worried that they would end in catastrophe.

Though Kohfield wasn’t accused or charged with any crimes, police took no chances and prevented him from attending the rally as he repeatedly had promised to do on social media after his confrontation at Mayor Ted Wheeler’s house.
