Police have identified the gunman who murdered 32 of his fellow students as 23-year-old Cho Seung Hui, a legal alien immigrant from South Korea.

Police also report that Cho apparently legally purchased one of the firearms used in the shooting last month. That is a loophole that needs to be closed.

There's going to be a lot of finger-pointing in the days and weeks to come. Especially after it was revealed that Cho's "creative writing" was so disturbing that school officials referred him to counseling. In the final calculation, however, this is just one person's fault: Cho's. Undoubtedly lessons will be learned from this incident. But, no matter how hard we try and how well we prepare, it's extremely difficult to stop someone who is determined to do evil.

Please continue to pray for the victims, their families and the survivors.
