The FBI and various thug US departments are systematically using face recognition to recognize masses of people. In some cases, they match everyone they find.

New York City is preparing to match the faces of everyone that drives in and out of the city.

This creates a danger of total tyranny. I think Stalin is a better comparison than Hitler. The practice should be illegal.

No one (and that includes the FBI or any thug department) should be allowed to keep photos of everyone, or a large fraction of the population, neither alone nor in cooperation with others, nor allowed to take photos of everyone that passes a certain point or object except under a very specific court order.
