IIRC - USA is a lot more arbitrary and less interested in the customer safety (and open for bribery, sorry I mean lobbying) and USA also has a good amount of stuff for sale that's not allowed in EU.
There's quite a few articles and videos on the subject, but it's been a long time since I read or watched any.
That's always been the craziest thing to me about the US police system. In Finland the police is not legally allowed to lie to you about facts. They can lie about themselves and whatever, but not wholesale invent out of the thin air and gaslight people into believing that they did something.
