Who needs a new 'law' when it's already written into the US CONSTITUTION?!
"...the US Senate killed off a proposed law that would have restricted some of the NSA's intelligence gathering on Americans"
This was a total BS congressional manoeuvre that is entirely irrelevant. Here's why:
The Fourth Amendment to the US Constitution:
"The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."
IOW: All Congress did was admit that they're constitutional ILLITERATES. The NSA's broad collection of US citizen data within the USA is unconstitutional. What the US Congress is supposed to do in response is SHUT DOWN the NSA's unconstitutional behavior. That requires NO new law.
Worthless US Congress, Red or Blue.
