What do the Dept. Ag., Railroad Ret. Board, TVA, Office of Personnel Management, CPSC, and U.S. Fish and Wildlife Service have in common?

Regardless of how people feel about Nevada rancher Cliven Bundy’s standoff with the federal Bureau of Land Management over his cattle’s grazing rights, a lot of Americans were surprised to see TV images of an armed-to-the-teeth paramilitary wing of the BLM deployed around Bundy’s ranch.
They shouldn’t have been. Dozens of federal agencies now have Special Weapons and Tactics (SWAT) teams to further an expanding definition of their missions. It’s not controversial that the Secret Service and the Bureau of Prisons have them. But what about the Department of Agriculture, the Railroad Retirement Board, the Tennessee Valley Authority, the Office of Personnel Management, the Consumer Product Safety Commission, and the U.S. Fish and Wildlife Service? All of these have their own SWAT units and are part of a worrying trend towards the militarization of federal agencies — not to mention local police forces.
“Law-enforcement agencies across the U.S., at every level of government, have been blurring the line between police officer and soldier,” journalist Radley Balko writes in his 2013 bookRise of the Warrior Cop. “The war on drugs and, more recently, post-9/11 antiterrorism efforts have created a new figure on the U.S. scene: the warrior cop — armed to the teeth, ready to deal harshly with targeted wrongdoers, and a growing threat to familiar American liberties.”
