SAN DIEGO — Border Patrol agents will be allowed to continue using deadly force against rock-throwers, the chief of the agency said, despite the recommendation of a government-commissioned review to end the practice.

The Police Executive Research Forum, a nonprofit group that advises law enforcement agencies, recommended that the Border Patrol and its parent agency, Customs and Border Protection, stop the use of deadly force against rock throwers and assailants in vehicles, Border Patrol Chief Mike Fisher said.
