The U.S. Customs and Border Protection agency has announced new guidelines following a spate of deadly shootings by agents on the northern and southern borders. At least 19 people have been killed by border agents since 2010. The victims include at least six Mexicans killed on the Mexican side of the border. Sixteen-year-old José Rodriguez was reportedly shot from behind no fewer than seven times last October for allegedly throwing rocks at an agent. The new changes include a training program that will emphasize the defusing of threats instead of resorting to deadly force. In a statement, the American Civil Liberties Union called the measures inadequate, saying: “The biggest missing piece here is clear and transparent accountability for officers involved in use-of-force incidents that lead to serious physical injury or death. Without a commitment to end the culture of impunity at CBP, the agency’s good first steps will lead nowhere.”
