The police can, in fact, operate cameras in public spaces and they have done so for decades. ALPRs have been widely deployed since the 1990s.

I'm frequent surprised by how many people think that privacy laws block the police from recording their activities in public. For whatever reason, Flock is getting a lot of press, but this is hardly a new field.

ANPR has not been widely deployed since the 1990's in the US and the US court system has consistently held that the degree to which a technology automates monitoring, searching, etc is very relevant to whether it violates people's reasonable expectations of privacy for very obvious reasons.

> However, ANPR did not become widely used until new developments in cheaper and easier to use software were pioneered during the 1990s. The collection of ANPR data for future use (i.e., in solving then-unidentified crimes) was documented in the early 2000s.
