The way it is worded makes it seem as if it's against the provision... which it is... until you read the second paragraph(lines 9-13).
That section as I read it, and apparently Amash and several others, says that you can't detain an American indefinitely unless we are in a state of war or other state of "emergency" or by act of congress.
We are ALWAYS in a state of war. So this amendment is all but useless.
The wording is so bad that even lawyers are going to argue what this really means.
Tools of war are not always obvious. The worst weapon is an idea planted in the mind of man. Prejudices can kill, suspicion can destroy, and a thoughtless, frightened search for a scapegoat has an everlasting fallout all of its own.
