On what basis are you asserting that no explanation for her detainment was provided? Or by explanation, do you mean a public announcement? But let's say for the sake of argument that no explanation was provided, even privately to her and her attorney. I would agree that's bad, even if it's legal in the case of visa holders. But why should that cause us to make assumptions about the reason? And if we're going to make assumptions, why this particular one? Why not assume she was detained because an officer didn't like the color of her shoes?
