Awful.
And the terrible thing is, there's probably already somebody somewhere planning to "outdo" what this nutcase has done.
I'm usually against the death penalty, but why on earth should this individual be allowed to live his life of "celebrity"? There's no doubt that one day in the future he will fill the newspapers about "why he did it", or "he has changed", or whatever. I hate it when the likes of Charles Manson and Mark Chapman give newspaper interviews; captive but famous.
Get rid of them permanently and let the rest of us get on with life, I say.
