We are at war with this garbage. The only reason they are alive is that we wanted the information they had. Otherwise they would have been shot on sight. I do not see the need for a trial. If your humanity requires it, knock yourself out! Just make sure they receive wartime handling and wartime sentences.
Traitors can and have gotten the death sentence for the influence their leaking of classified material had. Terrorists are at least that bad.
"An error does not become truth by reason of multiplied propagation, nor does truth become error because nobody sees it." - Gandhi
Capital Punishment is state sanctioned murder.
If we kill them, they will be considered martyrs by their fellow terrorists.
We must never allow them to achieve this.
Prison for life without parole is better.
