The FBI conducted a raid Tuesday morning in Fort Lauderdale, Florida and arrested a far-right knave who was known for collecting weapons, threatening violence, dressing like comic book character The Joker and making antisemitic comments on social media.

According to the South Florida Sun Sentinel, the FBI’s Joint Terrorism Task Force and a SWAT team busted Paul Miller, 32, for a 2018 charge for being a convicted felon in possession of a firearm. The FBI did not provide any other information.

However, Miller’s social media accounts are peppered with threats of violence, videos of him holding guns and expressing hatred for Jewish people.

In one video, he claimed to be “trying to build” an army and expressed a desire to “gas” Jews.

Several other of his videos show him waving Nazi flags and discussing how he got beat up outside the New York Republican Party’s headquarters on the Upper East Side in October 2018.

Miller was also known for trolling users on the video chatting platform Omegle and dressing up as the Joker, spewing horrific antisemitic conspiracy theories.

Neighbors told the Sun Sentinel they saw FBI agents taking several boxes which appeared to contain guns out of the house.

Miller faces a maximum penalty of ten years if convicted of the single gun charge.
