Power like that is just too easy to abuse...which is precisely why the whole "Get a Warrant" concept got cooked up in the first place. Sure on some, isolated occasions, certain options might have potential usefulness. But this is why we also have the option of not crucifying someone if they happen to step over said line ... and that is fine. Moving the line OTOH is not. If officer X is willing to bet their career on an illegal wire tap/search/etc. that subject X is indeed a terrorist...Okay... But they better be triple thick double chocolate fudge with sprinkles and a cherry on top sure that they're right or they will be getting strung up in the town square.
