I heard a prominent (well-respected) legal expert on the radio a couple of weeks ago who made the exact opposite point -- he said that in this particular case it would have been much harder to obtain an FISA warrant than a criminal warrant.

The whole reason for the creation of FISA warrants was to make them easier to obtain than criminal warrants against terrorists, that no actually probability of any previous criminal action need be shown. The expert you saw was smoking something, and it wasn't tobacco.
