A week ago, Ars Technica had a writeup on NSA metadata collection, saying that the FISC had approved Obama's tweaks. What I couldn't figure out, though, was why anyone might think the court wouldn't approve them.
They approved MORE blatantly unconstitutional collection, so why would they not approve making it a hair less so? Really, the changes were basically in the "who cares?" zone, they were so minor. But I can't think of any possible way the court would say no.
