Yeah, but why have they refused to be interrogated? They were in a foreign country for several years (known for terrorists and obviously Bin Laden is hiding out there), so why can't they answer a few questions? Our country is at war here, we have to take some precautions!!
They don't have to answer a few questions. It's called the Fifth Amendment. Our country is at war ? Show me the declaration of war and I will accept that as reasons for some limitations, but you NEVER bar citizens the right to enter their own countries.
