The department paid tribute to Deputy Derek Pope, who last week was named the National Sheriff's Association Deputy of the Year.
Pope rushed into the apartment building where parolee Lovelle Mixon was hiding after the deadly traffic stop. Mixon was shot and killed.
"It's an honor and privilege and a humbling experience my concern and my fear is it distracts from the sacrifice of the four officers last year," Pope said.
Pope also credits the work of the Oakland SWAT officers who were with him.
Pope is the first sheriff's deputy from California to ever win the award in its 25 year history.
