As many as 700 occupy protesters gathered outside of San Quentin State Prison on Monday for a national day of action called "Occupy the Prisons."

Via:

The protest began at noon and protesters dispersed peacefully around 4 p.m.. A prison spokesman said San Quentin was on lockdown and that prisoners were being kept in their cells.

Organizer Barbara Becnel said the protesters were calling for a number of reforms, including the elimination of solitary confinement, the death penalty and California's "three strikes" law, and an end to the practice of trying some juveniles as adults.

The crowd included activists Sara Shourd, Shane Bauer and Josh Fattal, who served time in an Iranian prison after being arrested by Iranian authorities while hiking along the Iraq border in July 2009.

The Occupy movement is seeking change at both the state and federal levels, and are planning an "Occupy the Justice Department" action in Washington, D.C., on April 24.
