Oh, so I'm guessing you've never seen an IRS police car before? "Tax enforcement"? Saw my first one when I was a teenager. Only seen two in my life. But yes, they do have a militarized wing. In fact, every goddamn government agency has a militarized wing. The fucking place is literally out of control and I don't see how it can continue to function.
We're just one big (something) away from collapse. Mark my words.
