Frank Roper was hospitalized in Denver on Saturday with severe lacerations to his face after pushing a motorcycle cop off his bike. The incident came after the officer allegedly charged his Harley into a crowd of Occupy protestors, prompting outrage. Clashes took place between protestors and police — who employed rubber bullets and pepper spray — when a previously permitted march was shut down. This weekend saw Occupy protests turn violent nationwide, with clashes taking place in Oakland, Nashville, Atlanta and San Diego. Some legal experts have begun making motions about First Amendment rights violations.
