A political catch 22.
We say NSA is overreaching it needs to be stopped.
The feds send in the FBI to investigate.
We say the FBI is just as bad as the NSA.
The thing is the FBI, NSA etc... They are not trying to actively get rid of our rights. However their mandate is our security. Unfortunately Liberty and Security don't play nice with each other, more Liberty means people get to do more what they want and that could mean infringing on others security.
These groups are doing their jobs when they try to get more information. However what we lack is proper leadership to stand up and make the tough decision of saying, you are reaching too far, and we need to insure we keep personal liberty.
No they're NOT doing their jobs. More Data != Better.
They have access to information, their problem isn't that they need more data, They need to understand the data they DO HAVE so that they can analyze it properly for any threats. THEN when they have a specific threat they can request the additional data they need.. BUT only once they've actually identified a REAL target.
