One should not expect any change to come from the U.S. government itself (which includes Congress), whose strategy in such cases is to enact the pretext of “reform” so as to placate public anger, protect the system from any serious weakening, and allow President Obama to go before the country and the world and give a pretty speech about how the U.S. heard their anger and re-calibrated the balance between privacy and security. Any new law that comes from the radically corrupted political class in DC will either be largely empty, or worse. The purpose will be to shield the NSA from real reform.
