Guantanamo Bay, torture and the long road to a 9/11 trial Front Burner

It's been almost 20 years since four jets were hijacked mid-air and crashed into the twin towers of the World Trade Centre in New York, the Pentagon in D.C., and a field near Shanksville, Penn., killing nearly 3,000 people.

Today on Front Burner, longtime national security reporter Michelle Shephard on the preparations for what could be the trial of the century.
