From TechDirt:

The ACLU’s Jameel Jaffer alerts us to a district court ruling in NY that effectively says that by merely agreeing to AOL’s terms of service, you’ve waived your 4th Amendment rights. The case is the United States v. Frank DiTomasso, where DiTomasso is accused of producing child porn — with most of the evidence used against him coming from AOL. DiTomasso argues that it was obtained via an unconstitutional search in violation of the 4th Amendment, but judge Shira Scheindlin rejects that, by basically saying that AOL’s terms of service make you effectively waive any 4th Amendment right you might have in any such information.

All the more reason to use services like Silent Circle and encrypt your email.
