Lovelle Mixon, a parolee with an "extensive criminal record," killed three Oakland, Calif., police officers and gravely injured a fourth in separate encounters Saturday that resulted in Mixon's being shot to death. Initially, he gunned down two officers during a routine traffic stop. After an intense manhunt led to a nearby apartment building, Mixon, who was wanted for violating his parole, shot the other policemen with an assault rifle. The last time an officer was killed in Oakland was 1999.
An estimated 2,500 to 3,000 antiwar protesters demonstrated in Washington and northern Virginia Saturday on the sixth anniversary of the invasion of Iraq.

The president says he plans to withdraw roughly 100,000 of the 138,000 troops now serving there by summer 2010.
