Is Trust Justified?

I had confidence that George W. Bush would not use intelligence the Federal government garnered for crass political motives but still had reservations about authorities invading my/our privacy routinely. Now, I am far less confident, in fact I am quite concerned that America's spy agencies might not be protecting average citizens, but collecting information that may be turned against us. I am not suggesting that Barack Hussein Obama and his minions are "disappearing" opponents the way Latin American dictators did, but I would suggest that we have plenty of cause for worry.
