Let me make this as clear as I possibly can.
Yes. This is supposed to target terror suspects. It applies to "detainees".
However, detainees can be American citizens. As was posted above, you only need be "suspected of aiding terrorist organizations", and you qualify to be stuck in a prison cell indefinitely without charge. Because there is no HC in such cases, they don't actually need any PROOF of those suspicions. Essentially, a government agent could come to your house tomorrow, take you away without saying a word, lock you in a prison and keep you there for months, if not years, simply by telling your family you're "suspected of helping terrorists". And it would all be completely legal.
As for examples of this happening, well, the bill isn't even in effect yet, it's awaiting presidential signature. However, recently, a Canadian citizen was transported by US authorities from the US to Jordan, where he was interrogated and tortured for an extended period of time. He had done nothing, had no terrorist connections, and was never charged. Eventually he was released once they were satisfied. Is that okay? No. But as of now, it's legal. And it applies to you too.
Let's face it, you're probably only in trouble if your name is Abdul Muhammad Jibar. If you're Geoffrey Hamilton, you're probably not going to end up in a cell somewhere. Especially if you carry an American passport. But isn't it a bit disconcerting that if, somehow, you WERE, you would no longer have the right to representation, to a trial, to anything? Let me finish with a quote.
"Alongside our famous individualism, there’s another ingredient in the American saga, a belief that we’re all connected as one people. If there is a child on the south side of Chicago who can’t read, that matters to me, even if it’s not my child. If there is a senior citizen somewhere who can’t pay for their prescription drugs, and having to choose between medicine and the rent, that makes my life poorer, even if it’s not my grandparent. If there’s an Arab American family being rounded up without benefit of an attorney or due process, that threatens my civil liberties.
It is that fundamental belief: I am my brother’s keeper, I am my sister’s keeper, that makes this country work. It’s what allows us to pursue our individual dreams and yet still come together as one American family.
E pluribus unum: 'Out of many, one.'"
