Most days, Ronald Branson and his wife take turns at the computer in the garage of their San Fernando Valley home, waging war against what they see as a major failing of their country’s court system.

Their Web site, www.jail4judges.org, blasts the “arbitrary abuse of the doctrine of judicial immunity.” They shoot off frequent e-mails to rally their troops, like the one last April when Branson praised a Nightline report called “Blaming the Bench.” “We are only now viewing the beginning of a looming showdown in this nation on this subject,” he typed to his audience, which he says numbers at least 1,000 people.
