I'm going to preface this by saying the whole Americanised ACAB stuff is silly. Not everywhere has a shitty, militarised police force like theirs. Where I am, my experience with the police has been pretty positive, even with me being an immigrant with darker skin.

But man, no.

If police want your data, they can ask you politely, and if you say no, then that should be it. End of discussion. People have the right to privacy.

Maybe the officer wouldn't do anything nefarious. But then again, maybe they will. You have no way of knowing what type of person that officer is. Even good police forces have plenty of shitty employees, so police powers should be limited to avoid them just doing whatever they want.

If there's a genuine reason to have your data, say you're implicated in some criminal investigation, then they can go through the proper channels and get a warrant.

Police absolutely should not have the power to just do whatever they like. If you let them, have that, it leads to shitty police forces like they have in the US and elsewhere.
