Yes, progress has been made. And its entirely possible that that progress was made because of people pressuring Obama to correct this situation, even in spite of those who tried to silence them (even right here in this thread).

People who try to silence voices raised in protest of human rights abuses are guilty of aiding and abetting those abuses.

On the subject of Mohamed's treatment in the UK... he is not now being held captive anywhere. That certainly has to be an improvement over being held indefinitely in Guantanamo.
