Washington Post has an article, seemingly focus on Cho’s Asian background. The article talked about possible movie influence on Cho Seung-hui. First Oldboy was discussed, but the author found it does not fit. Then he turned to John Woo(吴宇森) and movies with Chow Yun Fat(周润发), especially the movie “The Killer”.
This sounds like pure racial to me. Cho is asian, is Korean but that doesn’t mean he would watch Korea and Hong Kong violence movies. He has so many more violent movies made in USA as options. The author spend a lot of time analysing how similar Cho and Woo’s movies are. I was very disappointed to read this article. To me, violence are all the same.
