VTech tragedy

There has been reports by the press that the gunman had put an alarm note on a website (4Chen) were people can share their thoughts or files anonymously saying “I am gonna kill people in Virginia tech today” signed under “hey /b/”. That was controversial though, since the date was unknown. The articles mentioning that has all been removed.

However, I searched for this ID and I found out that it in a similar website (totse), there were some posts under “hey /b/”. This guy named “Katy” had some comments on VTech massacre, implying the gunman might have been right and those people might have deserved that! One post says: “I'll pray for the gunman.” Another one: “Most of those kids probley deserved it, kudos to the gunman.”

The fact that "hey /b/" has comments on 4chen (you can find it in "toste") proves that he/she is the one who put the famous post not the murmurer.
Ain't it scary that there are people out there, happy with what has happened in VTech?
