Here's a snip from his website.
In 1987, while peacefully blocking a military train at a U.S. Navy munitions base in California loaded with armaments headed for Central America, I received severe injuries and was almost murdered when the train chose not to stop.
The Navy train crew and their superiors knew in advance of our nonviolent three-member veterans' blockade and had a clear, 650-foot view as the train approached us at high noon on a bright sunny day.
Though expecting to be arrested and jailed by the nearby armed U.S. Marines and local police, we never imagined the conscious and criminal acceleration of the loaded train to more than three times its posted five-mile-an-hour legal speed limit. I lost both legs, suffered a fractured skull, multiple other injuries, and nearly lost my life as I was run over by the speeding train.
One of the other veterans dove out of the way at the last minute.
