I certainly did not expect the libertarian ideal of depending for protection wholly on private security, instead of on the state, to be first implemented in Los Angeles, of all places.
UPs police force is not private security in the usual sense. Those in CA are California peace officers, and all of them are also specially federally empowered for interstate operations.
And this isn't new, major railroads have had these publicly-empowered police forces since the late 19th century.
