Your own choice of words betrays your mindset, whether you realize it or not. You call the perpetrators of Columbine "psychotics". According to you Columbine was committed by 2 "psychotic kids", ...but it was "an Asian kid who did the killing in Vermont too."
Fact is, they were all psychotic, but by your own assessment, the one who did Virginia Tech and the one who did Vermont were not categorized as 'psychotic' ...they were categorized as 'Asian' kids.
Pointing out the ethnicity of a perpetrator is as ridiculous as pointing out the eye or hair colour of a perp.
My point is, people need to stop seeing & categorizing by ethnicity, and more by character.
