No, their not. For the second time, stop talking about them if you know absolutely nothing. Their just gangsters that disrupts shops and forces them into paying money since apparently 'kkangpaes' own the place.
I was using it as an example, i'm sorry for not knowing "nothing" about a Korean street gang. I was just naming countries off the top of my head which i'd heard had mafias/street gangs. Not really my field of buisness. Glad you've been reading up on them though!
