Be Very Afraid?

Orin Kerr has an interesting discussion of Sen. Spector's bill to revise FISA. It includes this scarey bit:

"If you don’t have a reasonable expectation of privacy in your cell phone calls, which those cases suggest is the case, Specter’s bill would mean that the NSA can tap every cell phone in the country of every US citizen, for entirely domestic calls, all without a warrant. This monitoring wouldn’t be “electronic surveillance” because (based on the cordless phone cases) the Fourth Amendment doesn’t apply."
