Don't forget the "we need a balance" statements, even though it's the U.S. government that has long moved away from that balance, and now just wants to be able to do whatever it wants, whenever it wants it, to whoever it wants, with no oversight.
But the 4th amendment is different than the 1st and the 2nd. It has balancing built into it, by only prohibiting "unreasonable" searches and seizures. It's as if the 1st amendment said "Congress shall make no law ... abridging the freedom of reasonable speech" or if the 2nd amendment said "the right of the people to keep and bear arms reasonably, shall not be infringed."
