Copyright and the US Federal Gov't

While I watch the news in Portland about Mt. St. Helens and its possible upcoming eruption, I’m seeing plenty of links to the volcano webcam on blogs. One of the blogs that stood out for different reasons is the Berkeley Intellectual Property blog’s post about the Terms of Service, copyright status, and law around Federal work entering the public domain. In the end, the author can’t prove that the webcam images are in the public domain, but draws the conclusion they likely should.
