Has anyone seen the Fourth Amendment?

It seems to have gone missing again. Perhaps it is just on holiday. The United States Department of Homeland Security now says that it can seize "laptops...hard drives, flash drives, cell phones, iPods, pagers, beepers, and video and audio tapes -- as well as books, pamphlets and other written materials" without any suspicion or probable cause.

America - it used to be such a nice country!
