Why does NYC even care? This tendency to govern in a controlling way is not just weird but plain unethical. I hope this goes viral and embarrasses them.
NYC government is peculiar, in that its size and scope is like a US state, but it also subsumes the functions of US cities and counties. The closest comparison in the US is probably LA County.
Thinking about it in terms of technology — during the pandemic the schools bought a million iPads. They also run a giant hospital system, the largest police and fire departments in the country, etc.
The net result is administration of a vast, sprawling (both horizontal and vertical) bureaucracy is complex, and the cogs in the wheel of that bureaucracy are simultaneously in your face and detached from reality. So you have a group of attorneys who see a threat in people posing in front of a camera.
You first paragraph raises some interesting points. It makes wonder if NYC police and fire is larger than that of some smaller countries in Europe, like Belgium or Netherlands. My guess: Yes!
Indeed, the NYPD has 33,000 officers and Belgium's armed forces have 24,000 serving plus 6000 reserve. They also have very similar budgets: $6b vs. €7b.
Agree in spirit, though again if it does go viral and they become embarrassed the most likely thing is they'd shut down public access to the cameras - which would be a lousy outcome for everyone.
My county has traffic cameras available online, though it's only static images updated once a minute or so. It's not that great but I still appreciate it, especially during winter weather. Every now and then if the weather seems bad I check the cameras to see what the roads look like before I head out. It's not a big deal, but I'd be a little annoyed if they took away public access because someone was trying to make some sort of statement or game out of them.
This is an opportunity for bullshitters (in a "bullshit jobs" sense) to be seen as "doing something" and get pats on the back without significant effort - at least less effort than doing other, actually valuable things.
