First of all this bill is assuming that the person convicted is guilty. One of the things about our trial system is that people are convicted of crimes that they did not commit in the heat of the moment.
Second the people who are with a person in jail would know their mind best. They should be given the same opportunity as anyone else to be rehabilitated. Terrorists are entitled to the same opportunity for early release as any other prisoner.
To date, no released terrorist has returned to terrorist activities against the U.S. — so there’s no reason to rule out the possibility of allowing early release for such persons.
Terrorists are less likely to return to their way of life than people who are let out all the time who have committed mass murder or are serial abusers. They are more of a threat than terrorists.
