This always happens

I stop reading the news for a few days, and newsworthy stuff happens.
The 4th amendment guarantees us the right to be secure in our persons, houses, papers, and effects, against unreasonable searches and seizures. Warrants shall only be issued upon probable cause, supported by Oath or affirmation, and the warrant must particularly describe the place to be searched, and the persons or things to be seized.

As if that weren't enough, the 5th amendment covers that again with, "No person shall be deprived of life, liberty, or property, without due process of law."

So WHY did a joint House-Senate conference committee approve a provision in the 2004 Intelligence Authorization bill that will permit the Federal Bureau of Investigation to demand records from a number of businesses--without the approval of a judge or grand jury--if it deems them relevant to a counter-terrorism investigation?
Do they think our Supreme Court is underworked? Do our congressmen not understand the constitution? It's not like it's a large document. You can breeze through it in less than an hour. It's not like a proper warrant is difficult to obtain, either.
The provision is absolute rubbish. Our congresspeople should not waste their time on it.
