I believe the ATF, DEA, FBI, HUD, HHS, CMS, SSA, FDA, CDC, DoE (both of them), OSHA, EPA, DoL, etc etc are all extraconstitutional bureaucracies run bum unelected officials regulating things the federal government does not have the constitutional authority to be involved in.
The level of taxation, power, and control the federal government exercises over the citizens of this country as well as the states far exceeds anything we declared our independence from the crown over.
