It reminds me of the Nazi saboteurs that were caught of the coasts of FL and NY (I think LI) in June of 1942. They were set ashore by U-Boat, on a mission to blow up military and civilian targets on US soil. They were apprehended virtually immediately, and none had been able to attempt their acts of sabotage, let alone successfully complete them.
They were all tried by military commission (yep, military commission), and all were found guilty. One man, a US national named Quirin became the defendant in the famous US Supreme Court case Ex parte Quirin, 317 U.S. 1 (1942). His life was sparred eventually, as was another US national who was caught. But, the remaining 8 (or 6, I can't remember) were executed as a result of the commission's guilty verdict. They were hanged until death in Washington DC on August 8, 1942 - roughly 9 weeks after they had been apprehended.
Today, we have people at Guantanamo that not only attempted sabotage and murder against America and her citizens, but were actually successful. None have been put to death, almost 10-years later.
I believe FDR made some remark about not wanting some sonofabitch filing a Habeus Corpus writ in that case.
