A staged encounter between the cops and the bad guys. Where the so called bad guys are actually just some innocent buggers, summa standing around, and are suddenly shot to the high heavens. It is done when the cops are under media and Government pressure to nab some porkipayyas or terrorists who robbed a bank or planted a bomb or something.
Senthil: You heard those bank robber bugger got shot last night uh?
Michael: What? When da?
Senthil: Ya mam! Yesterday night, next to my place, full cops at night da. Five buggers shot dead. Funny thing is i was up having one quarter and didnt hear any firing only. Plus cops told me to get inside and switch off the lights.
Michael: Dey, must be coz of your reeking Old Monk breath. Or must be fake encounter only.
