I don't think I'm implying the president has direct control over local authorities. I'm simply saying that policing in the US is complex and saying "it doesn't matter who you elect" clearly isn't true. The executive branch has huge soft power over how policing is done in the US. For example, the rise of militarized police is largely due to donated spare Iraq war equipment. The executive branch chose to donate this.

I think there's a lot more to it than that. There's also the matter of a lot of war vets becoming police officers, the approach to policing they learned in the military, and their lasting effect on police department culture.
