Linnen writes "CNET News.com writer Anne Broache reports that the head of the US Copyright Office considers the DCMA to be an important tool for copyright owners. '"I'm not ready to dump the anticircumvention," [Register of Copyrights Marybeth Peters] said in response to a question from an audience member who suggested as much. "I think that's a really important part of our copyright owners' quiver of arrows to defend themselves." The law also requires that the Copyright Office meets periodically to decide whether it's necessary to specify narrow exemptions to the so-called anticircumvention rules. (Last year, the government decided it's lawful to unlock a cell phone's firmware for the purpose of switching carriers and to crack copy protection on audiovisual works to test for security flaws or vulnerabilities.)'"
