Not necessarily. When I say a trial, I mean whatever the military considers a trial for this kind of person. I assume that would be different from a civil trial. Bottom line - I think we should either kill them or set them loose, I see no point in holding them in Gitmo potentially for years. What's the point? If they're dangerous, kill them, if they're not - let them go.
Okay -- I think I see your point and I'm sorry if I misinterpreted what you wrote.
You say you're comfortable with executions, but not with holding these folks in custody. It's hard to understand why execution is less objectionable than merely holding someone in a cell, but I don't want to belabor this point.
