Manuel Ramos and Jay Cicinelli were charged with striking Kelly Thomas with a baton and a stun gun in a beating that left him comatose. He died five days later.
Ramos' attorney, John Barnett, told reporters: "These peace officers were doing their jobs...they did what they were trained to do."
Orange County Dist. Atty. Tony Rackauckas said prosecutors would not pursue charges against a third Fullerton officer accused in the Thomas case. That officer's trial was pending.
