Ernesto Diaz, a 23-year-old U.S. citizen, was walking down Archer Avenue on Chicago's Southwest Side in late September when masked federal agents grabbed him, slammed him against a vehicle, and handcuffed him. Agents ripped out his earbuds and threatened to tase him when he moved. After about five minutes of questioning and inspecting his ID and Social Security card, agents threw his wallet on the ground and drove away. Diaz believes he was targeted based on his race and ethnicity during Operation Midway Blitz.
