Right. And the ACLU no has all they need to get him off scott free ... No photo of the crime was taken even though photographers were on the scene. The accused was attacked by a horde of strangers who had not been harmed by him in any way. The strangers searched his personal belongings without a warrant in violation of the fourth amendment. They injected him with chemicals without performing a proper screening of his medical history in violation of the eighth amendment. They bound him and denied him is right of freedom of movement in violation of the fifth amendment. No one read him his Miranda rights ... and he probably did not get the lunch he paid for ... nor a refund. All this, even though there was no true danger since later investigation showed his alleged shoebombs could not be ignited due to wet fuses. Which raises the final point: The guy is too dumb to stand trial if he doesn't even know enough to stay out of the rain while wearing shoe bombs!!! ;-)The passengers and crew were in hot pursuit.
In any event, the plane was outside the United States.
Further, no one had reason to believe that the fuse was wet, even if it was.
I don't see any constitutional issues.
