Humanity...should there be exceptions?

I just watched an interview of the US Attorney General and found myself greatly disturbed. He was answering questions about Miranda rights being read to people brought in under suspicion of terrorist activity and how that did not deter them from answering questions. (remember the "anything you say can and will be used against you in a court of law" clause) The attorney general is moving to have the laws regarding interrogation changed to reflect a "public threat" clause which would broaden the rights of interrogators if someone is suspected of terrorist activity, being linked to terrorist activity, or in any way plotting terrorist activity. This means if someone under those conditions who can be seen as "public threat" ie. able to do mass amounts of damage to the public or with information regarding that activity was brought in for questioning, the amount of force behind the interrogation could be greater than let's say if this guy was part of a child slave smuggling ring. Not only are we distinguishing the level of the crime based upon threat to numbers but also based upon global political arenas. is our government more shocked by a car bomb than perhaps 5000 children stolen for sex slaves? Does it make the child slave ring smuggler any more human than any man or woman accused of involvement with terrorist plots? Will this kind of law excuse some of the blatant racism that occurs when people of Arabic descent come to our country, or live in our country? We have profiling that occurs now that places anyone with a Muslim or middle-eastern last name under some sort of minor surveillance, either through the public eye or otherwise. This sort of law would build more hostility between the American government and its own people, not to mention the people of countries who end up being profiled along these lines. I am not saying that I agree with terrorism, but we should not change the rules of how we treat ANY human being under constitutional law. Those basic human rights, those inalienable human rights are why we have this country in the first place. The less human we treat anyone for ANY reason, the less human we become ourselves.
