all police departments that I am aware of in the U.S. are single hierarchy. The dual hierarchy is a military thing.
In the U.S. when there has been a draft (involuntary conscription) one is only ever drafted in to the lower hierarchy. The officer hierarchy was always strictly volunteers.

Also, even without a draft the lower and upper hierarchy have different induction methods. Military academy for the upper hierarchy, etc.
