Shane Kohfield, a Trump supporting former Marine, had his firearms confiscated by law enforcement last month under Oregon's new "red flag" law.
The FBI's Joint Terrorism Task took "extraordinary steps" against Kohfield last month after he threatened to "slaughter" Antifa in self-defense during a demonstration outside Portland Mayor Ted Wheeler's house, the Oregonian reported.
"If Antifa gets to the point where they start killing us, I'm going to kill them next," Kohfield reportedly said. "I'd slaughter them and I have a detailed plan on how I would wipe out Antifa."
FBI agents reportedly responded within days, forcing Kohfield to temporarily surrender his firearms — which included an AR-15, handgun, rifle, and shotgun — to authorities. He was also committed to a veteran's hospital for psychiatric observation.
Kohfield was never charged with a crime.
Oregon's red flag law allows a judge to issue an "extreme risk protection order" against individuals who law enforcement or family members believe is potentially violent to themselves or others. The "protective order" lasts one year, but can be renewed indefinitely.
Phil Lemman, Oregon's acting deputy state court administrator, told the Oregonian that judges have approved 98 "protective orders" since the law took effect last year.
What did Kohfield say?
The ex-Marine, who served two tours of duty in Iraq, told the Oregonian he understood why law enforcement targeted him.
"I looked unhinged. I looked dangerous and have the training to be dangerous," he said.
"I figured that the key to de-escalating the situation was to not be the most violent person in the room," he explained. "It was to be the scariest person in the room."
As far as protests go, Kohfield said his days of demonstrations are over.
