US Capitol rioter sentenced to 20 years - one of the longest punishments yet

A California man with a history of political violence was sentenced on Friday to 20 years in prison for repeatedly attacking police with flagpoles and other makeshift weapons during the US Capitol riot on 6 January 2021.

David Nicholas Dempsey's sentence is among the longest among hundreds of Capitol riot prosecutions. Prosecutors described him as one of the most violent members of the mob of Donald Trump supporters that attacked the Capitol as lawmakers met to certify Joe Biden's 2020 presidential election victory.

Dempsey, who is from Van Nuys, stomped on police officers' heads. He swung poles at officers defending a tunnel, struck an officer in the head with a metal crutch and attacked police with pepper spray and broken pieces of furniture, prosecutors said.

He climbed atop other rioters, using them like "human scaffolding" to reach officers guarding a tunnel entrance. He injured at least two police officers, prosecutors said.

"Your conduct on January 6 was exceptionally egregious," the US district judge Royce Lamberth told Dempsey. "You did not get carried away in the moment."

Dempsey pleaded guilty in January to two counts of assaulting police officers with a dangerous weapon.

Only the former Proud Boys leader Enrique Tarrio has received a longer sentence in the January 6 attack. Tarrio was sentenced to 22 years for orchestrating a plot to stop the peaceful transfer of power from Trump to Biden after the 2020 election.
