When Thomas didn't obey Ramos' commands to put his hands on his knees, Ramos started swinging his baton at his legs.

At a demonstration outside the Fullerton Police Department weeks later, one protestor told Reason TV, "You actually hear him calling out for his dad. It definitely did something to my heart hearing and seeing that."

After initial interest the media stopped covering the story. Local reporters lean heavily on public information officers when reporting on crimes, and the Fullerton...
