Amir Mohamed Meshal, probably a supporter of muslim extremists, was detained, transported and imprisoned by foreign governments, and while detained by them, claims to have been questioned and threatened by FBI agents.
It is plausible that he was questioned by US agents of some sort, just as it’s plausible that the US encouraged Kenya, Somalia, and Ethiopia to take the actions they did. In the end, however, he was freed, came back to the US, and sued the US.
This is a “he said, she said” kind of story. The fact that he was a supporter of the terrorist government of Somalia makes this about as interesting as Obama ordering the killing of US citizens abroad for being ISIS supporters.
What should be the limits of actions the US can take against its own citizens who aid organizations that want to kill Americans?
Because he is a citizen, and citizens have rights in our form of government. .Gov can't simply say, he is a bad dude, and have determined he is a bad dude without any open court or procedure. Being overseas does not limit .gov, they are still bound by the Constitution.
Something short of execution, after a trial, of course.
