Thomas Mooney
On July 22, 1916, a bomb exploded during the Preparedness Day Parade on Market Street in San Francisco, killing ten people and injuring forty. Thomas Mooney, a labor organizer and political activist, was convicted of the bombing along with Warren K. Billings. The problem was that the evidence was fabricated. Witnesses were coached or coerced, alibis were suppressed, and the prosecution built its case on testimony that crumbled under scrutiny almost immediately. Mooney was sentenced to death, later commuted to life imprisonment. He spent 22 years behind bars for a crime he almost certainly did not commit, becoming one of the most prominent political prisoners in American history.
The Bombing and the Frame
The Preparedness Day Parade was a pro-military demonstration at a time when the United States was moving toward entry into World War I. San Francisco's labor movement, which opposed the war, was a convenient scapegoat when the bomb went off. Mooney, born in 1882 in Chicago, had been a visible labor agitator in the Bay Area, organizing streetcar workers and participating in strikes. His prominence made him a target. Within days of the bombing, Mooney and Billings were arrested. The case against them relied on witnesses whose stories changed repeatedly, photographic evidence that was later shown to have been fabricated, and the suppression of testimony that placed Mooney far from the scene at the time of the explosion.
Twenty-Two Years
The falsification of evidence became apparent almost immediately after the trial, prompting an international campaign for Mooney's release. President Woodrow Wilson intervened in 1918, asking the governor of California to reconsider the case. The death sentence was commuted to life imprisonment, but Mooney remained in San Quentin. For over two decades, labor organizations, civil liberties groups, and supporters worldwide demanded his release. The case became a cause celebre of the American labor movement, cited alongside the Sacco and Vanzetti case as an example of political persecution masquerading as criminal justice. Governor Culbert Olson finally pardoned Mooney on January 7, 1939.
Free and Dying
Mooney emerged from prison a broken man. The 22 years of incarceration had destroyed his health. He died on March 6, 1942, less than four years after his release, at age 59. He was buried in Cypress Lawn Memorial Park in Colma. The actual perpetrators of the Preparedness Day Bombing were never identified. The case was never solved, despite Senator Dianne Feinstein's later attempt to reopen the investigation. What remains is the story of a labor activist imprisoned on fabricated evidence for 22 years, a reminder that the American justice system has been capable of producing political prisoners long before that term entered the popular vocabulary.
