The question is whose rights should the US not violate.
The answer, of course, is everyone's.
Human rights are not a not a grey area. Either you respect them or you don't.
Though there may exist loopholes in legislation that appear to make human rights violations legal, that does not make them acceptable. People that hunt for such loopholes barely classify as human themselves.
The US courts can only "protect" people in the US sphere of influence. If peoples rights are being denied, the question is not how the courts can protect them. The question is, why have those responsible not already been brought before the courts.
If, as the poll suggests, the US authorities are denying people their rights, then it is already too late. The courts are not the only arm of government that have to respect people's rights.
