GOF: Is Big Brother Watching?

The government has always found ways to track and "spies" on its own citizens and even citizens of other countries. This was even before the technological era occurred. Before computers there were still ways for the government to find out confidential information that citizen thought they have one idea about. With the invention of computers and Internet it just made their jobs easier. This in some cases make people citizens mostly think... How do they get a hold of such valuable information without their knowledge? There are way too many disclaimers and privacy acts for them just too have easy access to these thing. Which makes you wonder... When these privacy laws and acts are passed in congress do they create some kind of loop whole for themselves for later access?
