> Wait, are there actually people in the US who still assume that there someone has to get a warrant to investigate them under the auspices of terrorism or National Security?

What's amusing is how many people assume that the police ever needed a warrant to "investigate them." The police need a warrant to search your person or your property. The police don't need anything to investigate you, and need nothing more than a court order to subpoena documents from people who might have information about you. This has always been the way our system worked.

Depending on what exactly PRISM does, it may very well not require a warrant, any more than the police require a warrant to get your bank records or other kinds of information about you held by third parties.
