I think that's conflation. Having high visibility of an area so that cameras can be consulted for evidence can be, as you attest, a good thing. Being tracked over an indeterminate length of time, profiled, and maybe one day punished for thoughtcrime, is a very different beast.

And if you think thoughtcrime is far-fetched or paranoid, you aren't paying attention. Governments around the world are moving to crush dissent by limiting gatherings for protest, labelling/charging people as terrorists without having committed any terrorist acts, etc. What makes you think anyone will ever be able to organise against oppression, even if the cause is just, when one is treated as guilty without committing any crime?
