The EFF summarizes several systems of governmental massive non-internet surveillance in the US.

It doesn't mention remote-viewing cameras mounted at fixed sites, but these do massive surveillance in places such as New York City.

Merely putting limits on the use of the massive dossiers that these systems collect about each person is not sufficient to reduce our level of surveillance to below that of the Soviet Union. We need to eliminate these systems or redesign them so that they can only "see" court-designated targets.
