First off, my heart goes out to the murdered lady's family, no one would want their daughter to leave this world that way.
Secondly, I can understand how the media could potentially blow this story out of proportion into a culture hating exercise. Ultimately, negative stories sell papers but I'm hoping this doesn't happen, it would be a real shame. Since I got in to manga and anime, I have become interested into all aspects of japanese culture and that has undoubtably been a good thing for me. I can only wonder what kind of effect this will have on the expat community living in japan and those who may be thinking of teaching english there.
