The president met with about 40 family members and victims, who hold different views on his decision to close the prison in Cuba within a year. The exchange, which was sometimes passionate but never acrimonious, left some who were deeply skeptical of the administration’s decision to suspend military commissions at Guantanamo Bay satisfied that the president has not yet decided to abolish the current system of prosecuting suspected terrorists.

Obama told the group that he was only hitting the “pause button” when he sought the suspension of proceedings against 21 detainees, including Khalid Sheik Mohammed, the self-proclaimed mastermind of the Sept. 11 attacks. And he assured the group that he wants the swift prosecution of those responsible for the terrorist attacks and their facilitators.
