Thanks for the reasonable response.
I am personally for the death penalty, I believe your actions have consequence and you have to pay for that consequence (a liberal nightmare). There are crimes that are so horrendous that the only consequence that can be fitting is death. Considering the crimes that these men have been convicted of I think the penalty is correct.
As for the method of going about the death penalty, I think the current system is so overly complicated that it's almost designed to fail, and when it does fail it creates a terrible situation. Going back to something like the guillotine would be a good idea, while messy it is a quick, clean kill that is hard to botch.
