Since article does not do any attempt to answer these discrepancies, there is high chance the devil is in the details of definitions of those numbers.

That's an extremely paranoid approach to law enforcement, especially when according to basic criminal law, these citizens are supposed to be considered innocent by default. Mass automatic surveillance of this reverses the idea of innocent until proven guilty without actually aknowleding it. That's scary
