What part of "shall not be violated" did Congress not understand when it passed the Patriot Act and, later, the Protect America Act of 2007 — which further eased restrictions on domestic surveillance?
These laws could be reined in and the Foreign Intelligence Surveillance Court, which rubber stamps administrative requests for surveillance, could be made more transparent by having its decisions made public. This should be done at the very least.
But this is up to Congress, and keeping America safe is its top priority, one that trumps individual liberties. Even though the NSA program has been outed it will continue. Soon it will fall out of the headlines, people will forget about it and the utter disdain for the Fourth Amendment will continue until Americans themselves decide they've had enough.
In summary Surveillance laws can be reined in, and this should happen at the very least.
