A refusal to let them stand trial, will send a strong (bad) message to the world regarding the integrity of the USA. Christ,... every pr1ck and his dog is just waiting for us to blink and they'll be screaming for the International Court of Justice.
I can see the headlines now "It 's good enough for the Serbians, why not Blackwater"? It's a no brainer, we can't just go around the world protecting people who commit murder, regardless of what some politicians may think. There are people who want to crucify us just for being there, if we start carrying on like we are a law unto ourselves, we've lost it,..... completely.
Men were sent to the gallows in WWII for similar things, and I'm talking about the Allies not the Germans.
