Generally a cop’s remit doesn’t include extensive knowledge of law - that’s why we have lawyers and judges.
Expecting cops to have that kind of knowledge isn’t useful, and contributes to current problems.
Even the most well-intentioned, best-educated cop can make mistakes (as we all can). So simply never argue with them - let them arrest you without complaint (because if they’re going to arrest you, there’s nothing you can do that won’t exacerbate the situation), any such issues can only be resolved in court - that’s the place for arguments.
