You have it backwards arguing against the militarization of police means that more power & more accountability goes to city /town/state governments not federal authorities.
The federal govt. is using the offer of federal military equipment as the thin edge of a wedge to get local leo’s to work for “multi-jurisdiction task forces with the Feds in charge doling out money from confiscation of property that is sold at auction .
This is not only a militarization of policing problem but a law enforcement for profit problem as well.
It is a complex issue.
