On the night of May 16, 1967, police blockaded the Texas Southern University campus in response to a student civil rights protest. Amidst the high racial tensions, the confrontation escalated into an "Alamo-scale shootout," according to the Houston Chronicle. Police fired an estimated 3,000 rounds into TSU's Lanier Dormitory, where the students were blockaded. Law enforcement raided the building in the early morning hours of May 17, arresting 488 students—the largest mass arrest in Houston history. Two police officers were wounded and another, rookie Louis Kuba, was killed. A small group of students, known as the TSU Five, were indicted on charges of inciting a riot, assault, and murder. They were Charles Freeman, Trazawell Franklin, Douglas Waller, John Parker, and Floyd Nichols. Only Freeman was tried, resulting in a hung jury. A judge ultimately dismissed the case against all five defendants due to insufficient evidence, believing that Kuba most likely died from a ricocheting police bullet.
