Anthony Pacheco unexpectedly announced his resignation as of July 1, saying in a letter to Mayor Antonio Villaraigosa that he needs to return full-time to his law firm job. Pacheco has been president of the civilian police commission for two years. "In that time, he established himself as a cautious -- some would say too cautious -- but firm, unflappable hand, guiding the commission through sometimes delicate and sensitive debates over police policies and controversies," says the LAT's Joel Rubin.
