If you did you are / were a complete fool and here is why...
Our government, believe it or not, generally acts in the best interest of us. How do I know this? Because at a time in my life I worked for it.
You can site all of the lobbying abuses, sweetheart deals, back room dealing, etc. etc. but the general thrust of your argument would still be wrong
Senator A votes to have deal B go through and for the most part he does it for two reasons, re-election money or to get a project / company / entity to do business in his or her state because fundamentally his interests generally align with the people who elected him or her to office.
When it comes to national security everyone had a total freak out when a bunch of guys from Saudi Arabia flew airliners full of people into buildings.
Was the NSA kinda clueless? Maybe, were our politicians? Very much so, so they did what all politicians do, they gave an agency carte blanche and looked the other way while saying you had damn well better cover our asses from here on out..
What is really funny about this, is that the so called "Meta Data" is noting more than your phone bill. Ah but the chink in the armor are phones you can buy with a prepaid sim in them for cash. You don't know who made a call you just know that a call was made, so even that data is hard to deal with because you actually have to track the device down, put some eyes on the ground and search for 1 person out of the population of [insert large metropolitan area here ] to see who is using that phone. I think we could go a long way towards prevention of bad things my outlawing them. You want to buy a pre-paid cell phone, fine, we scan your photo ID so at least we have a picture of the person or perhaps a finger print. Do that and we catch half of the gang bangers tomorrow.
You see I really don't care who knows the number I made a call to or got a call from, what I do care about is them knowing the content of the call, and I am not even sure the new data center in Utah could hold all audio from every call made. What this is really is know if two baddies are talking to each other, or a baddie is calling a guy who works for the FAA, an airline, a company that manufactures chemicals that can be made into explosives, etc. you get the idea.
As to Diane Feinstein I think she should have to register as a foreign agent of Israel since she their US lobbying arm. I used to vote for her but have voted against in the last two senatorial elections and I am a Democrat!
