Just for the record, here's the U.S. Constitution's Fourth Amendment:

The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.

That's the amendment targeted by the FISA overhaul supported on a bipartisan basis in Congress, including by both major presidential candidates. For more details, the ACLU is always a good place to start. Here's a press release from Thursday, before the House voted to accept the new proposal.
