Dorner released a 6,000 word so-called "manifesto" on his Facebook page which outlined his distaste for the Los Angeles Police Department and made threats against individuals he believed were responsible for ending his career with the police force five years ago. The LAPD has assigned 50 protection details to guard officers and their families who were deemed possible targets.
Despite the costs, there are no plans to reduce the protection until Dorner is in custody, Los Angeles police Sgt. Rudy Lopez said.
Between the manhunt, protection details, and the need for additional security at Sunday's Grammy Awards, the Los Angeles Police Department enacted a tactical alert Sunday afternoon that would remain in effect through Monday; the alert can require officers to stay on duty beyond their shifts and asks them not to respond to low-priority radio calls.
