Yes. However, prison rape probably isn’t.

It appears you have, as I suppose left liberals are apt to do, slightly underestimated the leniency of the criminal justice system :) http://www.order-order.com/2008/05/ok-let-rip-in-comments.html

After all, if there isn’t enough space to keep suspected rapists waiting for trial off the streets, putting away an anarchist blogger would seem a rather low priority - entertaining as it would have been.
