Something You Hear A Lot

Goes like: "Well what about all these Guantanamo prisoners, these Arabs, who are dangerous people, who seek to kill Americans, but there's not enough of a case to convict them in a criminal or military court."

Hard to believe that you know they're dangerous people but there's not enough evidence to mount a credible prosecution. Unless it's some weird cycle thing where you imprisoned them before they were dangerous, but now they're dangerous because you imprisoned them, so you need to keep imprisoning them because they're dangerous.
