Re: Agencies shall, to the extent consistent with applicable law
"Perhaps, if it is illegal, they won't be able to do it."
that's the theory. I suspect actual practice will be much different than the FUD.
I also suspect that this was aimed primarily at ILLEGAL IMMIGRANTS, and not an excuse for NSA spying on the world. In other words, if a gummint program guarantees some level of privacy protection, such protection would NOT apply to illegal aliens. People here legally [including tourists] would most likely continue to be given the same kinds of rights and respect as before [even though our Constitution does NOT guarantee such things].
The REAL measuring stick should be this: the U.S. should treat foreigners the SAME way that U.S. Citizens are treated overseas. Just sayin'...
