But you could be wrong about him being guilty, so executing him would be a mistake.
Everyone who is convicted is subject to the same standard of proof in court … evidence must prove to jurors guilt beyond any reasonable doubt.
If every convict is subject to the same standard of proof, then just what do you propose as a criterion for separating the "really for sure" guilty and the "probably but only maybe" guilty? Because, you see, if the person is "maybe" guilty then they shouldn't have been convicted in the first place because the justice system is infallible … right? Every other convict in prison is proven guilty to the same standard of proof …
Do you suggest that a confession is certain guilt? Well, first problem is that under certain interrogation conditions, confessions can be extracted and later proven incorrect. And then you have the problem - if confession is "certain proof" and thus leads to harsher punishment (ie capital), don't you think that confessing to crimes will rather quickly stop?
As to Olsen's taunting of victim's families, seems that can be dealt with fairly easily without capital punishment. Really. Just takes a little imajinashun.
