If you think this is extreme, read the next paragraph:
Tanks, grenade launchers, armored vehicles, and assault rifles are just a few of the items that have been transferred from military control to municipal police forces. Law enforcement agencies need only to arrange and pay for shipment in order to receive the items of their choice (pdf). One particularly egregious example is found in South Carolina, where Richland County's sheriff acquired a tank with 360-degree rotating machine gun turrets. Sardonically, the vehicle has been named "the Peacemaker".
All I have to say is this really necessary?
What are police forces and the military planning for?
