Britain, ex-EU, has the biggest mass surveillance in the world in place. London, the global leader, has more cameras per capita than Beijing. I wonder what other cities in the EU have high numbers of cameras per capita as well?
That said, number of cameras is not the only metric. Every house and business having their own camera backed by VHS tapes and watched occasionally by bored humans is much less of an issue than one camera per road but they’re all networked and backed by hard drives and scanned by AI.
