Most crime doesn't happen in the view of streetlights. Fraud, wage theft, domestic violence… how do cameras help with any of that?
Just because fraud exists, this does not mean street crime does not exist. What a strange argument.
Your argument is that if cameras don't help with fraud or wage theft or domestic violence, they serve no purpose.
Cameras may impact street crime, and street crime is rampant in many U.S. cities. White collar crime has no bearing on this, and it's irrelevant to the discussion.
