The bad very much outweighs any good that these cameras are alleged to help with. Fucking traffic violations?

Okay, maybe tracking a murderer etc. might be a good use of the system, but the ratio of that happening, and what they are being used for is ridiculous.

I reject the notion that mass surveillance has any valid use whatsoever, even including tracking murderers. The mere existence of the system has chilling effects on the non-criminal citizenry that makes it absolutely categorically unacceptable regardless of what alleged benefits it tries to claim.
