The state should be able to to monitor everything .
I can't disagree more. This is a crazy position. Imaging
These data should be encrypted and only be viewable in crime cases .
Right, because there has never once been a single case of data being leaked, hacked, or used inappropriately? The fact is if this data is gathered, it
will be used against you, regardless of whether you have committed any crimes.
As for the terrorist attacks let's consider the Boston marathon bombers . These guys were caught by examination of the videos .
Videos from businesses and individuals, not from government surveillance cameras.
