The movement to improve policing in the U.S. gained significant momentum in various cities, particularly in places like Ferguson, Missouri, following the 2014 shooting of Michael Brown. Additionally, cities like Minneapolis became focal points for police reform after the death of George Floyd in 2020, sparking nationwide protests and calls for systemic change. These events catalyzed discussions on policing practices, accountability, and racial justice across the country.
I assume you refer to 'policing' in the sense that the US is often referred to as the 'worlds policeman'. No it shouldn't but then it isn't. The US does on occasion act in concert with other powers under the auspices of the UN, but that responsibility is to the UN, specifically the Security Council of which it is a member in any case. As to policing in general, if the US were responsible for policing it would have a difficult job (as there are no hard and fast laws that apply universally to many things). Moreover it would be being derelict in its duties, there are many areas where the US is not involved that need policing. Of course the US would also be guilty of police brutality (for taking action against people without reason or legitimacy). So no, the US should not and is not responsible for policing, it does however often act in its interests and protect its interests abroad, on occasion that is expressed to its own public as policing (it gives the right impression in propaganda terms).

The relationship between the United States government and policing organizations affect police practices by responding to police needs. Policing organizations lobby the Congress every day.

If by "Native American communities" you are referring to only those communities actually located on Native American lands (i.e.: reservations) - the policing there is under the jurisdiction of the Tribe itself. The efficacy of the policing is only as good as it woujld be in any smaller community within any of the rest of the US, which is to say, some of it can be very good, and some not quite so good. Since they are self-governing nations they receive the type of law enforcement (on the reservation) that they wish to enforce.
