They still need to capture incidents in the station itself.

This argument justifies CCTV surveillance of all public places.

Is that what you intend to be arguing for? In any case, there needs to be more nuance in the discussion than a one-liner.

I think the quantity of surveillance matters. When it’s just a few places, then it’s a minor intrusion on liberty. When it’s a lot of places, it’s a major intrusion that will facilitate the (further) rise of authoritarianism.

> This argument justifies CCTV surveillance of all public places.

Well, yeah, I think that was super obvious, no?

> In any case, there needs to be more nuance in the discussion than a one-liner.

Not really. Super public busy places like train stations ought to be surveilled. The benefits far outweigh any cons.

There is far more nuance than this.

What counts as a "super public busy place" ? The airport? The bus terminal? The local library? All major roads that experience rush hour traffic?

Who is the person who says where the cutoff line is? What if that authority wants to move the line to include everything? Or nothing? Do they even need to provide notice to the public of their actions?

Who should be able to access to all this footage? Public? Government investigative branches only? What about the system administrators?

Does this footage require attestation to prove it's legitimacy in a world where AI can generate footage?

How long should this footage exist for? Do I have to trust not just current admins and their superiors but all the people who may be in those roles in perpetuity? IE do I have to trust people who haven't even been born yet?

Is it allowed to be centralised, so people can easily be tracked from one site to another for every step outside their house? Or should each site have separate data housing with access terms to match so that tracking a person is a significant task?

.. ..

There are a lot of concerns. You may argue that there isn't a lot of nuances because you have a set idea of how it should all go. But others may differ.

> There is far more nuance than this.

There's just....not. It's a pretty well established concept by now. For almost 50 years or so.

> What counts as a "super public busy place" ? The airport? The bus terminal? The local library? All major roads that experience rush hour traffic?

Yes to all of these.

> Who is the person who says where the cutoff line is?

Not a person, but a sound methodology ideally. Kind of like what we've mostly been doing even if it isn't formalized.

> What if that authority wants to move the line to include everything?

Yes, the slippery slope is a problem, agreed. That's why we need to be vigilant in responding to government plans.

> Do they even need to provide notice to the public of their actions?

In a civilized democracy, they should.

> Government investigative branches only?

Yes, pretty much.

> What about the system administrators?

Not if it can be avoided.

> Does this footage require attestation to prove it's legitimacy in a world where AI can generate footage?

No.

> How long should this footage exist for?

3 - 6 months is typically standard.

> Do I have to trust not just current admins and their superiors but all the people who may be in those roles in perpetuity? IE do I have to trust people who haven't even been born yet?

You have to trust the system is accountable.

> Is it allowed to be centralised,

Ideally, no.

> Or should each site have separate data housing with access terms to match so that tracking a person is a significant task?

Bingo.

> There are a lot of concerns. You may argue that there isn't a lot of nuances because you have a set idea of how it should all go. But others may differ.

I'd argue your concerns have already been addressed by current systems that have worked fine for decades.
