Back in the 60s and 70s, president Park Jung-hee had the police (and military) scrape the entire country and threw every gangster they could find into re-education camps. That was South Korea back in the days when it was getting its head screwed on straight.
Wannabe gangsters piss me off. I swear, the only thing that keeps me from getting to them is, ironically, the law. Ain't worth the legal trouble to grab the f***er's spray can and stick it up his ass.
