Can any of the legal scholars on FR point out the constitutional authority for police and police departments?
10th amendment
Tenth Amendment restates the Constitution’s principle of Federalism by providing that powers not granted to the National government nor prohibited to the states are reserved to the states and to the people.
Your neighbors want this.
If anything, the Constitution PROHIBITS the type of police forces we have now. They are the equivalent of “standing armies” used to control the citizenry, which were an anathema to our Founding Fathers.
When the modern police forces were first established in the mid-nineteenth century they were challenged as unconstitutional but, as we know, the courts decided differently.
