Najibullah Zazi, a 24-year¬old Afghan entered a plea of ‘not guilty’ this week to charges of conspiracy to use weapons of mass destruction, in what's being called one of the most serious terrorist threats since 9/11. His arrest came amidst a number of other terror-related cases. How serious were these threats? Are the cases a result of improved law enforcement? What role did the Patriot Act play? Also, the US and its allies talk to Iran about its nuclear program, and seismologists analyze several deadly earthquakes that have rocked different parts of the globe. Conan Nolan guest hosts this rebroadcast of today's To the Point.
