Often we wish to believe that good behavior in an environment that is strictly controlled represents a renouncement or contrition for believes or behaviors that contributed to their incarceration. Good behavior in confinement may mean that there may be no opportunity for further terrorist behavior. The confinement itself may offer greater radicalizing influences and greater access to those who have similar beliefs. Incarceration may offer greater training and networking. This is one major reason we should not make incarceration a growth industry. They become universities for the advancement of criminals. Many of the people who find themselves incarcerated may have chosen a different path if not forced to live with the truly violent elements in our society. Back to topic: No, the release of a terrorist before they serve their full sentence should be based on individual evaluations and release is granted by the same authority the pasted the sentence.
