"WHERE ON EARTH DOES THE CONSTITUTION GIVE THE FEDERAL GOVERNMENT AUTHORITY TO ESTABLISH A POLICE FORCE?"
The constitutionally limited power (hint) federal government has the power to police enforcement of federal laws that are reasonably based on its very few, constitutionally enumerated powers. The feds can police for counterfeit money for example, which probably wouldn't be the problem that it now is if the corrupt feds had respected constitutionally-mandated gold and silver coins.
On the other hand, the Constitution's drafters distrusted the federal government that they established to the extent that they ordered the feds to STAND DOWN to domestic violence unless a state's leaders formally request federal help in stopping violence, evidenced by the Constitution's Article IV, Section 4.
"Article IV, Section 4 (4.4): The United States shall guarantee to every State in this Union a Republican Form of Government, and shall protect each of them against Invasion; and on Application of the Legislature, or of the Executive (when the Legislature cannot be convened) against domestic Violence [emphases added]."
THE BIG PROBLEM with today's unconstitutionally broad federal police power is this imo. Ordinary citizen voters who have probably never really studied the federal government's constitutionally limited powers have too much voting power, evidenced by the ill-conceived 17th Amendment (17A; popular voting for federal senators). Consequently, when crook politicians running for federal Senate promise constitutionally naïve voters every politically correct civil right and constitutionally indefensible social spending program under the sun to try to get themselves elected, voters take the bait elect these crooks.
The crooks then establish the unconstitutional social spending programs and constitutionally indefensible rights that they promised voters on the campaign trail to get themselves elected, such programs based on Congress's abuse of 16th Amendment powers (16A; direct taxes), totally defeating the purpose of a constitutionally limited power federal government by doing so.
Are we having fun yet? 8^P
"16th Amendment : The Congress shall have power to lay and collect taxes on incomes, from whatever source derived [emphasis added], without apportionment among the several States, and without regard to any census or enumeration."
"Congress is not empowered to tax for those purposes which are within the exclusive province of the States." —Justice John Marshall, Gibbons v. Ogden, 1824.
The congressional record shows that Rep. John Bingham, a constitutional lawmaker, had clarified the federal government's constitutionally limited powers as follows.
”Simply this, that the care of the property, the liberty, and the life of the citizen, under the solemn sanction of an oath imposed by your Constitution, is in the States and not in the federal government [emphases added]. I have sought to effect no change in that respect in the Constitution of the country.” —John Bingham, Congressional. Globe. 1866, page 1292 (see top half of third column)
"From the accepted doctrine that the United States is a government of delegated powers, it follows that those not expressly granted, or reasonably to be implied from such as are conferred, are reserved to the states, or to the people. To forestall any suggestion to the contrary, the Tenth Amendment was adopted. The same proposition, otherwise stated, is that powers not granted are prohibited [emphasis added]." —United States v. Butler, 1936.
So it can be argued that abuse of 17A power by citizens who don't have a clue about the fed's constitutionally limited powers has been instrumental in fostering the growth of unconstitutionally big federal government.
Since Congress and likewise renegade states have repeatedly proven that they are enemies of the people imo, it is now up to Democratic and Republican Trump supporters to effectively "impeach and remove" ALL (exceptions?) state and federal lawmakers and executives in November.
In fact, it's up to us Trump supporters to take the first MAJOR step in draining the swamp by supporting hopeful Trump 47 with a new, Constitution-respecting Congress, new state lawmakers too, not only so that he will not be a lame duck president from the first day of his second term, but will support him to quickly finish draining the swamp.
Supporting Trump to finish draining the swamp includes supporting him to put a stop to unconstitutional federal taxes by leading the states to repeal 16&17A, effectively "seceding" ALL the states from the unconstitutionally big federal government by doing so.
Finally, let's not allow the anti-Trump media try to fade our memories of what we witnessed on July 13.
