When you outlaw Chainsaws, only outlaws will have Chainsaws...
From The Huffington Post:
"The video shows Dinnen -- who was boozed up and on drugs at the time -- waltz casually into the pub, flailing his weapon and holding it near patrons' faces. He was looking for a man who had thrown him out for lighting a cigarette inside the pub, despite a smoking ban in the area, several news outlets reported.
But customers weren't having it.
Bar patrons armed themselves with kegs, pool cues and barstools, flinging them at Dinnen from a distance. He ripped open the arm of Adrian Pryor, 32, with the chainsaw, but realized during the melee that the guy he was actually looking for had already left."
