A joint investigation by the Washington Monthly and the Investigative Fund at The Nation Institute has found over the past five years U.S. border agents have shot across the border at least 10 times, killing a total of six Mexicans on Mexican soil. The killings have gone unpunished after a court ruled the Mexican victims have no standing to sue in U.S. courts since they died on their own soil.

Border Patrol officers should not be firing over an international border and killing citizens from another country for no reason. Officers that murder innocent civilians should be held accountable for their crimes. They should not be protected because they are killing civilians from another country.
