Should the CIA be allowed to use any means necessary to gain information?

The CIA should be allowed to use whatever means are necessary to extract information from terrorists. If we aren’t allowed to use even some of the tactics that they use on us we may never be able to get information from them, which in turn could make us more suseptible to another terrorist attack.
“More power to the CIA,” states a student that declined to give information. “If it’s going to protect my wellbeing, then I want them to do what they have too.”
Some would argue against letting the CIA to use any means necessary to extract information. We would be lowering our standards as Americans to treat people the way the terrorists do. The thing that most people that are in support of this don’t understand is how we can let the terrorists chop off our soldiers heads, starve journalists, and kill them ruthlessly, but for us to use certain tactics such as swirlees, titty twisters, indian burns and wedgies among other things. Even if such techniques as making prisoners listen to loud music, not being allowed to read their book of religion, or even to make them eat food that they are not accustomed too.
Most of the torture that the CIA wants to do is not physical harm, what they want to do is issue psychological warfare---they want to get into suspect’s head to extract information leading to our nation’s safety and security.
Another item that people bring up is that the suspects should be treated as well and if not better as Americans. These people are being treated a certain way because of the way they have been acting. Suspected terrorists should be treated the way they are and should be forced to torture or better be able to give a good answer to why they were doing what they were.
Some also argue that the Geneva Convention should be applicable to the suspects that we apprehend. Why should we give them the convience of the Geneva Convention if they have not agreed to abide by the convetion themselves? They use their own means of torture to gain information from us, which is to be considered inhumane, but when our tactics are used on the enemy, immediately accusations of war crimes and inhumane torture are brought to the table.
What will be considered inhumane next? Forcing them to listen to heavy metal, jazz or even the Backstreet Boys? It seems that if the government tries to put more sanctions on the way that we can treat the enemy we will lose this war faster and lose more men and women here and over on the battlefield.
