U.S. Customs and Border Protection Agent Charles Exum shot U.S. citizen Marimar Martinez, who was warning others about immigration enforcement agents in Chicago's Brighton Park neighborhood, five times on October 4, after their cars collided. Martinez said the federal agent's vehicle rammed her car.

U.S. District Judge Sara Ellis on Thursday handed down a historic order that further restricts federal agents’ use of force during their deportation campaign in Chicago.
