Why wasn't he stopped before his murder spree?

Mass murderer Cho Seung-Hui did everything possible to let the world know that he was preparing to massacre students at Virginia Tech. The murderer even alerted the media of his intended action. The reason why nothing was done to curtail mass murderer Cho Seung-Hui was simply because he was NOT a "far Right" or "Right Wing" or "Christian" conservative. His anger directed at the same people that Islamic extremists and Left-Wing Liberals direct THEIR anger toward. As a matter of fact, mass murderer Cho Seung-Hui could have been a member of Al Qaeda.

If mass murderer Cho Seung-Hui was a "far Right" or "Right Wing" or "Christian" conservative, he would have been institutionalized after the Virginia court declared him "mentally incompetent" and would have never been able to buy firearms!

Because mass murderer Cho Seung-Hui was NOT a "far Right" or "Right Wing" or "Christian" conservative, the judgment against him was not made public nor put on an information system so that a gun dealer would NOT sale him a gun!

This is yet another example of Left-Wing Liberalism fine destructive work...
