I struggle to understand this. Isn't this what an election does? One administration controls the military, then another one does. So... the US, every 4 years?
I feel like this comment romanticize "power" in a common (yet, to me, very odd) way. We take power away from police officers all the time: "desk duty". As a group, we give power to the national guard ("mobilize") and take it away ("demobilize") all the time. I understand that police have a lot of political will behind them, but why is this problem all of a sudden a fundamental dynamic of power rather than a policy choice we as society continue to make?
