The danger of large amounts of data collection cannot be over stressed, this information can be and may have been used to blackmail political figures in power, supreme court members, or simply private citizens who speak out, WW2 history tells us evil exist in government we simply do not want to go down this road, for me I'm sad that 50% of the American people believe the collection of this data is good and or keeps us safe. Personally I would rather accept some danger and live free.
