Via this How Appealing post, I read this interesting editorial in the Washington Post, titled "The 4th Circuit v. Mr. Bush."
The editorial concludes:
"But keeping a man locked up, even at his own request, so that his challenge to his detention remains viable, is no way to vindicate his rights. Mr. Padilla has been asking for years to face trial; the government has finally - belatedly - agreed. The Supreme Court should not let the 4th Circuit get in the way."
