I'm for the trial. If KSM is being tried strictly for the World Trade Center and Pennsylvania then it's a federal and civil matter. If it's for the Pentagon and/or the USS Cole, then yes, they need to be tried by a military court. To be honest the only difference between Ramsay Yusef and KSM is that Yusef's bomb wasn't powerful enough. The intent and loss of life were still achieved and he was tried by a civilian court and found guilty.
