After riots broke out in Ferguson, Missouri, in 2014 following the fatal shooting of a black teen by a white cop, and police responded in tactical combat gear to largely unarmed protesters, many began to question the militarization of America's police forces.
Overall, American Transparency estimates there are more than 200,000 non-military federal officers and security personnel not attached to the Pentagon, which is a force larger than the Marine Corps, with its 180,000 personnel.
"The recent growth of the federal arsenal begs the questions: Just who are the feds planning to battle?" the author of the report, Adam Andrzejewski, wrote for Forbes.
The totals that federal agencies racked up is startling, the reports states, racking up "$313,958 on paintball equipment, along with $14.7 million on Tasers, $1.6 million on unmanned aircraft, $8.2 million on buckshot, $7.44 million on projectiles, and $4 million on grenades/launchers."
Digging into the specifics of what some of the more benign agencies are spending is equally as eye-opening.
The report states: "The Animal and Plant Health Inspection Service spent $4.77 million purchasing shotguns, .308 caliber rifles, night vision goggles, propane cannons, liquid explosives, pyro supplies, buckshot, LP gas cannons, drones, remote controlled helicopters, thermal cameras, military waterproof thermal infrared scopes, and more."
Former Senator Tom Coburn, American Transparency's honorary chairman, said he believes non-military federal personnel who should be subject to an assault weapons ban, not the general public.
Coburn, speaking to CNBC, said: "The government itself has become a gun show that never adjourns."
