Ever hear of Aldrich Ames? CIA guy giving secrets to the Russians. US citizen. Not one warrant issued in the entire investigation, including searches of his home.
I am certainly not defending Ames. In defense of their practices, legal council (this happened under Clinton) said that the President has "inherent authority to conduct warrentless searches" in areas of national security.
What exactly does "inherent authority" mean? It can only mean that the authority comes from the Constitution.
And just for fun, here's a nice link to a story which goes into a radio address by Clinton that authoized warrntless searches in crime ridden housing projects. No foreign intelligence application here -

By the way, I do not believe that either OSHA or the EPA requires any sort of warrant to inspect private property. Also, if you own a gun shop, you can be inspected by law enforcement at any time with no warrant issued.
Prudence, I am not sorry to say that yes, if you are in phone contact with known terrorists, I am fully in support of you being monitored.
