Complaints filed about ICE shooter (AP) SANTA ANA, Calif. - A federal agent who was killed after shooting his supervisor in a California workplace confrontation had been the subject of complaints by immigrant advocates who accused him of using coercive tactics with immigrants after a raid. In an amended complaint filed Thursday, the American Civil Liberties Union of Southern California asked a federal court in Los Angeles to order Immigration and Customs Enforcement to turn over records related to the 2010 raid overseen by agent Ezequiel Garcia.
