OhmyNews.com reports that residents of Boo-Ahn are fighting in the street (Korean) to prevent Korean government's plan to build a nuclear waste processing plant there.
Weapons used in protests like this have recently escalated from sticks and occasional Molotov cocktails to more effective tools to keep police at bay or push them out of the way.
I don't exactly know where it started, but I think it was when ex-members of a secret military commandos clashed with the police while demanding that government compensate properly for their sacrifices.
They used their training to make deadly weapons out of everyday things and other citizens learned from them. Boo-Ahn residents are using propane gas, burning tires, and bamboo sticks against clueless police who has sticks and shields.
Darker side of progress, I guess.
