P.J. O’Rourke’s book Holidays in Hell has a chapter (I think based on a Rolling Stone article) where he covers rioter-police interactions in Seoul. He was quite impressed at the level of organization on both sides.
Here’s an article with some quotes from it.

Thanks, that was interesting. P.J. O’Rourke called Koreans the Irish of Asia for their joy in a good fight. :-)
