A Chicago Tribune analysis of Operation Midway Blitz, a federal immigration enforcement operation, found that of 106 people arrested, only nine faced pending felony charges. The vast majority had charges dropped or never filed by prosecutors. Federal judges questioned agents' credibility, and a grand jury unusually refused to indict three defendants. Cases included a 70-year-old Air Force veteran, a man with intellectual disability, and multiple protesters arrested at demonstrations or in traffic altercations. Federal prosecutors acknowledged applying heightened standards due to concerns about jury nullification and the operation's chaotic enforcement pace.
