Obama's decision to close Guantanamo

As most people may already know Obama made one of his first decisions as president in his announcement that he would be shutting down the prison facility at Guantanamo Bay. It really does not matter what die of this issue you fall on, everyone has to admit that this is an extreamly bold move by Obama and makes a very serious statement.
What Obama is saying in making this move is that the USA will not tolerate the kinds of conditions that were in place at Guantanamo. Even though the people at Guantanamo were suspected terrorist and other criminals Obama still made the strong statement that NOBODY deserves to be treated the way that those in Guantanamo were being treated.
Personally I feel that the decision to shut down Guantanamo was a poor one by President Obama. The people that are in this prison are there for a reason, it is not the kind of prison that you end up in for being in the wrong place at the wrong time. There are some suspected terrorists in Guantanamo, I imagine it being very difficult to pin charges on a terrorist when many of their dealings are shady and their comrades are not quick to talk or throw anyone under the bus. That may be the reason why many of these people remain suspected terrorists and not charged terrorists at this point in time.
Another main reason I feel Guantanamo should stay in operation is that the type of people who are there hold information that is dangerous and if we find out that dangerous information there is a chance that we can stop another attack from occurring. Since many of the prisoners do not divulge information when politely asked what kind of future terrorist attacks they are planning we as a country are forced to turn to more severe measures to find out this info.
A third reason I feel Guantanamo should stay in operation is because the people leaving Guantanamo are going to hate us more than they originally did (if that is humanly possible). These people will be let free now so that they can plot further against the USA. If we are letting these people free we should have some kind of a program where these prisoners who were hurt are talked to and dealt with to remove SOME of the extreme amount of hatred that they will understandably have. This is not an easy task but something we would be dumb to at least not attempt.
I believe that some people are so savage due to the brainwashing that they have endured over the course of their lives that letting them free (since they are not technically charged with anything yet) would be outright dangerous for the rest of the world.
