I think even in an anarchist utopia, people might accidentally create a hierarchical / police like institution to deal with particular issues. But your example sounds more like current day private investigators / investigative journalists, who occasionally get tasked by their community to do police investigator things. I wouldnt really call that a police force.
I think the more relevant thing to me would be, what additional information are they able to access, why are those actually stored in the first place, who can normally access those etc. Because that might actually be the thing that would be the actual target of bad actors and those that want to have power over others.
Edit: Ah yeah for me it passes the vibe check for something that anti authoritarians might implement to deal with a serial killer or something, especially after they abolished the police.



I think it would be a great experience for you. If you are super worried you could try on a used device or be open to switch back, as both iPhones and Pixels ahve decent reselling value.
You sound like you are not relying on the Apple ecosystem, so you shouldnt lose out as much as others with lots of other Apple devices/services.
Also GrapheneOS has been the best Android experience I had, because it taught me not tl rely on Google services, embracing FOSS alternatives and actually caring about hoe my phone works / what data my apps can access.
