shooting at the virginia shool tech

i would like to write a little word about the shooting at the virginia shcool tech. i had never listened about one thing like that. people who go to shoot the others in a public space it's something that happens sometimes. but, mostly of the time, people who do that have individualists reasons. this time, the gay who did that, denounced the poverty and the discrimination from rich people against poor in the same school. this is new. the reason is a social one. for sure, usa have to control the arms. for sure too, society must change. we don't know but if the society didn't was so much discriminating, maybe this kind of situation could be avoid.
