Just like we need Federal Government limited in their powers, we need local government limited to some degree as well. Some of this junk they issue the local police is so certain officers (not all, or most) can use the equipment for their Rambo low self esteem. It's very very rare that a local police organization need armed presonnel carriers and various other military weapons. If their egos require using that equipment, then join the military.

Ask yourself this: do you really want the local Harpersville police to have that equipment? Yes, a local police force should be able to have normal sniper type rifles, whatever pistols they want, body armor, etc. But, do you really want one of these rouge officers (small faction of the force, but they do exist) to have access to military weapons if something goes awry in this country and the local DA decides to align themselves with a federal government that you might disagree with???
