The NSA is supposed to act on foreign targets (which helps me in no way), but the NSA is not only listening to foreign communication. That was part of the lie Clapper told congress and then extensively discussed. FISA court is not a real court in a "rule of law" sense if it is non-public and creates secret law. Both is the case. Also, maybe even more importantly: The FISA court did not even decide on individual surveillance acts under PRISM, but about the program in whole. Both together means that in no way there is a court oversight for this kind of surveillance.
