If your police department has one of these then they are dangerous jackasses. Fire them.

Police who are doing their job are trying to minimize violence and their overt impact on the city.  They're trying to promote peacefulness not drive tanks through town.  Skinhead 'criminologists' have become so detached from the communities that they are paid to protect that they have turned themselves into domestic arms of the Army.  Which of course is unconstitutional.  Dumb thugs.
