On Twitter, numerous people recall that the US insisted on trials for Nazi war crimes at the end of World War II. They cite this as precedent that says that Bin Laden should have been similarly tried. But they're mixing things up too much, the situations are not comparable.
Suppose one of the Nazis had escaped or been acquitted. There was no danger of them re-opening Auschwitz or invading Poland again. Germany was defeated and Europe was in ruins. The next thing to do, no matter what, was to rebuild Europe. At most the Nazis could have escaped justice, and therefore would fail to serve as an example for future would-be war criminals. The Nazis were done, and Germany was knocked out.
Pretty sure I don't have to finish this, but just in case. Trying Bin Laden would have created an unprecedented spectacle, and would have given him control of everything until there was a resolution. Bin Laden was a master of media. He would have known what to do with such an opportunity. And since we know his intentions were to kill Americans, that can't help but mean more dead Americans. Maybe a lot more dead Americans.
