A renewed hunger strike at California State Prisons has mushroomed to nearly 12,000 participants, as prisoners protest tortuous conditions, including a policy that makes inmates snitch on other prisoners or be held in solitary confinement indefinitely. The strike comes at a time when the California prisons are under attack for unconstitutional conditions of confinement, and in Federal receivership. But the prison authorities are threatening to punish strikers and have already expelled two of their attorneys from attending prison talks.
