Not saying that it's a perfect system, there will always be problems because there's not such thing as a perfect law, just a less imperfect one.
The difference between the EU and the US is the people. The mindset is different, that's why things can be so lax and still work.
FYI all continents and societies around the world are simultaneously burning and blooming with success. What changes is the bubble you're on. If you go on YouTube you can find an equal amount of videos and people saying that the US/EU is horrible/amazing. It all depends on the person and the person's values. I'm happy here and I completely understand those that are not, same for the the people in the US.
Of course it has issues though. Not so much in the way you seem suggest here though.
They do occasionally do coordinated operations on usually enforced laws. Like set up control points at universities and check if all bikes passing by are legal. But they won’t regularly pull you over if you’re missing a reflex or similar, unless your bike is extremely unsafe.
I.e. in practice it gives everyone the right to have their right to their own likeness enforced. Which most of the time isn't taken too serious, but is an important feature at times.
I'd sooner have that than people being a pain in the arse because they're explicitly allowed to exercise rights at the cost of society.
Both concepts cut both ways.
Seems like the smarter thing to do would be to outlaw "the problem" and not leave every single person's safety/freedom entirely up to the whims and benevolence of police.
each person has a different feeling in how they are comfortable with having their pictures published. therefore the only sane thing to do is to give each individual the right to control that.
it's like copyright. by default all rights are reserved, but i can give permission to copy if i wish.
But your cops can already do this as well, they’ll just name it disorderly conduct instead.
You could of course always choose to not break the law to begin with.
