No need for a person to do the "surveillance".
It is all automated, and much closer to a "social score" than criminal surveillance.
Example:
There he is! on freerepublic again! How many hours this month!!
There, he looked at a gun article four times this month! Very unsocial activity.
Link to his phone location data.
He visited a Christian church (not an "acceptable" one either) three times this month.
How much money is he taking from the state with his pension?
Look! he disparaged the LBGQT agenda, again.
The score is reaching a point, a human may want to look.
Perhaps his online services need an "adjustment".
I’m too old to be “adjusted”. And I’m old enough to have the attitude that the end isn’t all that far anyway. You just can’t scare an “old fart” with notions of death or dying.
