Rioter who attacked police at US Capitol gets 20-year sentence

WASHINGTON — 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 Jan. 6, 2021, riot at the U.S. Capitol. David Nicholas Dempsey's sentence is one of 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.
