This video, apparently shot in Mumbai, shows concerned citizens fighting back against some very brazen people pissing in public. The Batmen of urine (we don't think they're cops, anyway) use a big tanker truck to patrol the city and unleash a torrent on any public urinators they come across. Public urination is so bad it's sprung vigilante opposition.
The stated purpose of the Pissing Tanker is to eradicate public urination as a whole—"you stop, we stop"—but at the very least, it should keep people from pissing in places where a freaking tanker truck can fire a water cannon at them.
