"Batman vs. Vigilante: No Contest" from Gotham Underground #8 (DC, 2008) by Frank Tiere, J. Calafiore and Jack Purcell
It was a big gang war mini-series set in Gotham that had the Penguin snitching on other Batman villains for the Suicide Squad, and because Gotham City doesn't have ENOUGH gang warfare, threw in Tobias Whale and Intergang for good measure. Who comes out on top? The status quo, I guess. The 9-issue series also features a violent, splashed-filled fight between Batman and Vigilante, which might as well be a completely pictorial debate about gun control.
