Martinez’s shooting caused nationwide outrage, particularly after it was revealed that Exum had bragged about shooting Martinez. “Read it,” he wrote in one message after being sent an article about the incident. “5 shots, 7 holes.” He continued: “I fired 5 rounds and she had 7 holes. Put that in your book boys.”

The videos released on Tuesday shed further light on why prosecutors dropped charges against Martinez rather than try to bring a case against her to trial.

One of the videos released on Tuesday shows the perspective of a federal agent sitting behind Exum as he drives an SUV in Chicago. As drivers appear to honk at Border Patrol, one of the agents in the vehicle can be heard saying, “do something bitch.” About twenty seconds later, a Border Patrol agent says: “It’s time to get aggressive and get the fuck out because they’re trying to box us in.”
