SAN DIEGO (AP) — U.S. Customs and Border Protection held off Thursday on deciding whether to equip agents and officers with body cameras, saying more study is needed after a yearlong review by the nation's largest law enforcement agency. The Southern Border Communities Coalition, a group that has strongly criticized Customs and Border Protection over its use of force, said agents and officers have killed 40 people since January 2010. A 2013 report by the Police Executive Research Forum, a nonprofit group of law enforcement experts, was critical of the policies and tactics of the agency, which commissioned the report.
