I don't like how you worded that sentence at all. I know this probably isn't your intention, but you make it sound as if the South Korean government sent a trained killer to America in order to do this. He was a troubled college student who happened to be Korean-American (he had been living in America for quite some time before the incidents, so I assume he was a naturalized citizen.) To me, the fact that he is Korean has little do with any of this.
yeah, that statement is pretty much the most wrong thing you can say at this point, concerning asians (which, as said, shouldn't have any bearing on the matter). but i'm pretty sure there are way more other korean and korean american students out there that are fearful of anyone that actually thinks the way DragonFireKai is right now.
i do recall the s. korean president expressing his country's sorrow and schock and offering condolences, which could almost be taken like an apology for cho's actions. not a good look for them right now. but don't get it twisted, they're not responsible.
