I was friends with the US military police because they guarded our military intelligence compounds and facilities. Once, we were out in the ‘ville and we stopped to say “hi” to the South Korean police at the joint US/ROK police station. The Korean police had an old Korean woman, somewhere between 45 and 85, strapped to a wooden chair and they were throwing her pretty violently against the wall. I asked what she did wrong. They said she didn’t have any identification on her.
Yep, that sounds like Koreans (North or South). My description of the differences among East Asian cultures relates them to Star Trek. The Japanese are like Vulcans, subdued and reserved (until they have a couple drinks under their obi), the Chinese are money (and food) obsessed like the Ferengi, and Koreans are Klingons. Don’t piss off a Korean and expect him to let it pass. In Japan they’re known for nose busting head butts. And of course in LA, they protected their businesses from rioters with rifles from the rooftops.
