this is a cross culture situation

You know, there was a incident of gun in America on April 16th. The incident happened at unversity of Virginia. The criminal was a student of the university, and he was a Korian boy. He killed about 32 people with guns. The article say that he is a quiet and very unsociable boy. Then, the article tell that there were some paper of slander for him and he seemed that he was somtime cursed by other students. However what he did criminal act was never justified.
The reason why I think this is a cross cuture situation is that there is hardly a incident of gun in Japan. And, Japan has gun control law, so Japanese are prohibited to take a gun. However when the incidet happened at Virginia, the incidet of gun happened in Japan. Though we Japanese have a gun control law, sad to say there is a few incidents of gun. I am so sad that that things happen.
I red yomiuri newspaper, April 18th, the article was written first page.
