One fine day in 2004 Marvin Heemeyer snapped. Completely.
He built himself a tank and went out for a drive, and the town of Granby, Colorado was never the same again (some of it was not as tall as it used to be, so to speak).
You might not be able to fight city hall, but given enough time, heavy equipment, and sufficient batshit crazy, you can flatten that sucker - which is almost as good.
That's a special breed of crazy Marvin's got going on there. But, arguably, Marv had an excuse, click on the YouTube logo and read the comments on the original post, some of those folks need to be darted with a tranquilizer gun.
