While I personally feel that the death penalty is not necessary in the vast majority of cases,

Kadagar, depriving someone of their life after due process and appeal as punishment for the crime of poaching someone else's life is not murder. Your phrase was pithy, but inaccurate.

I was quite serious about firing squad being the best method. Presuming you need to execute at all (and note above that I do not in most cases), something that generates a nearly instantaneous death seems the kindest method.
