Opinionated - totally agree that the kid was mentally ill and wanted to end his life in a way that would have a huge impact on life in the US.

I too, wish sometimes they could interrogate these shooters before they deprive them of their own life. Our friends and we have had discussions about what is the greater punishment.. life in prison with no chance of ever being free again or ending the person life.

It's led to some interesting discussions... religious beliefs, life after death.. Heaven and Hell, prison conditions.

In a case like this, killing him instantly was the only choice, given he wasn't done with killing.
