Tipped off via the intrepid kodi, we have more on the Guantanamo plans for an execution chamber.
There also are plans to build a permanent modular detention facility, to imprison detainees who might be sentenced to indefinite terms, and an execution chamber should any be sentenced to death, he said.
If this is accurate, and the article quotes named individuals in the military, they have at the very least developed a process and procedure for military tribunal executions. And, in fact, it’s been posted.
Any lawful punishment or condition of punishment is authorized, including death, so long as the prerequisites detailed in reference (a) are met.
The above-mentioned reference (a) is the Military Commission Order No. 1, which is available here (as a PDF). It refers back to this Presidential order for authority. It should be noted that these tribunals are limited to non-US citizens, although it includes citizens of some of our allies.
I should also note that, on reviewing the orders referenced above, that the military has outlined a fair system of trials. Without spending more time thinking about it, I wouldn’t argue that the tribunal system itself is unfair. I am more concerned about a judicial system established by executive order, for reasons involving separation of powers. (There’s probably something to be said here about the system of military justice for our military personnel; I will summarize by observing that becoming subject to that system is a matter of personal choice.)
