This is also from the Washington Post:
Justice Anthony M. Kennedy was traveling in China and was unable to make it back in time for the ceremony; Justice David H. Souter was also out of town. Court officials said both men will be in Washington for the chief justice's funeral tomorrow.
"You are hysterical -- they didn't skip anything."
Who's hysterical? I didn't write the article, the Post did. Plus, where was Souter? He had 2 days to get back. It's not like it was his 4th cousin on his step-mom's side. Maybe the poster who said Souter was protecting his house from seizure was right.
