I think a few details and some background info were left out of that post in order to stick to the action. Either way, I am certain that something happened, it was wild as hell, and Firepower! was there. He is a good dude, not some 14-year old video-game geek.
The story makes me appreciate our fine American cops, though. Many other parts of the world do not have it as good as we do.
Buy a cop a doughnut and thank him for keeping the goblins in check, y'all.
