Judging from the press coverage, today's ID check protest in Denver was not quite as impressive as I was imagining. According to the Denver Post, the courthouse rally featuring Deborah Davis attracted "a dozen supporters," some of whom planned to join Davis in boarding a bus bound for the Denver Federal Center. According to the Rocky Mountain News, when Davis refused to show her ID at the gate (there's no mention of supporters), the bus was stopped, and five passengers who were willing to comply were switched to another bus. It sounds like Davis plans to continue this ritual until she gets arrested again, since the government's decision to drop the original charges against her prevented her from mounting a legal challenge to the ID policy.
