Gotcha. So people who are found guilty of heinous crimes should be summarily execute without any delay or appeals. I can't see any problems with that kind of system.
when there is effectively zero question of guilt, and you can safely and rationally apply a standard that is past "beyond a reasonable doubt" and into the territory of "without any possibility of doubt"? i would say yes.
people seem to act like "beyond a reasonable doubt" is the highest standard you can achieve, which is absurdly ridiculous.
i say death penalty, but without the decades of waiting, and without all the tediousness of humane methods.
fact is, this guy can never be allowed to be reintegrated into human civilization, i think everyone agrees with that whether you think he should be put to death or not... the common consensus is that he should be removed from society for the rest of his life.
in that case, i don't feel any need (morally or otherwise) to spend the time and energy required to keep him alive but securely separated from the rest of the world, as far as civilization is concerned life in prison vs. death has no practical difference, so go with the one that requires less effort.
i don't care about what he did, i'm utterly unmoved and indifferent to the act itself or the fallout from it, i just see it as a simple matter of practicality.
that, and the fact that putting a vaguely arab looking guy who bombed a marathon into a US maximum security prison is probably going to result in beatings, rapings, torture, and most likely death sooner rather than later anyways.
IMO being carted out of the court-house and getting a couple of bullets into the back of the head would be substantially more humane than throwing the guy into a pit where he'll more than likely be physically and mentally destroyed slowly and painfully.
