It's been a rocky start for Denver’s new manager of safety, Ron Perea. He recently claimed  a video showing Denver police beating two men contained "nothing" that would lead him to believe excessive force was used. Then, amid public outcry, Denver police, citing new information, reopened their internal investigation into the officers' behavior. On Sunday, Perea came under scrutiny again as more than 200 people, including local religious leaders, gathered in front of Denver's new jail to remember Marvin Booker, an inmate who was killed in the custody of sheriff's deputies in July, and to demand that Perea resign or be fired by Mayor John Hickenlooper. Perea tells The Denver Post  he won't resign but he will meet one of the protesters' demands by temporarily suspending the use of "carotid restraint"---the sleeper hold that was used on Booker. Late last week, Booker's death was ruled a homicide, after it was learned that he was restrained and Tased by deputies. Five deputies involved in the incident continued working until that ruling came on Friday but are now on paid administrative leave, according to 9News . Protesters are also demanding the video of Booker's death.
