He's a US citizen; he at least should have gotten a trial in America.
You going to send in the troops to Yemen to get him. It was a target of opportunity. We had Bin Laden in our sights several times and never pulled the trigger. That is a risk I would not take again.
I don't care if this guy was a former Presidential of Freedom award winner. He declared war against the US and sanctioned the murder of Americans. Further, his fingerprints have been on dozens of plots going back a decade. This is a war. Many US citizens served with the Nazis and Japanese too- If he wanted his trial he should have surrendered himself off the battlefield.
