> Putting up speeding cameras on public roads is not “unlimited surveillance” or “cameras everywhere”

Not by themselves, but public roads are a huge portion of everywhere when you look at person-hours spent in public.

Street corner cameras are also neither unlimited nor everywhere. But the combination of those two gets extremely oppressive.

Even just one is enough to track almost all your movements. Everyone's movements are not supposed to be in a database somewhere just because they moved through public spaces. And sure lots of those cameras are not centrally connected today, but the "it's public" argument allows it just fine.

They definitly can be. That's the slope. Where do you stop. Any totalitarian worth thier salt can easily make that leap. Use monitoring to curb one type of crime and "undesirable" behavior, why not use it for other types and before you know it, your entire existince is monitored in detail just to make sure you're acting exactly the way "they" want you to. That's how it works. The "I have nothing to hide" is a long debunked argument.
