Korea has nothing to do with this...

Look, this guy was insane person.

I mean... Why would he do this unless he was mentally retarded.

This has nothing to do with nationality because he was living in America for a while.
Unless maybe racism??? Probably not.

The solution to this watch out for these things... I mean I see these things often here in American countries with shooters and other craps.

People need to be more cautious and have more regulations for guns.

My opinion is that this shooter was insane and many other shooters before him.

This is Korean/canadian by the way.
