US Muslims on ISIS - As the nation marks the anniversary of the 9/11 attacks and President Obama outlines his strategy to defeat Islamic State militants, ISIS, American Muslim groups this week joined together to reaffirm their condemnation of violent extremism waged in the name of religion. Host Bob Abernethy and Managing Editor Kim Lawton talk with Haris Tarin, Washington Office Director of the Muslim Public Affairs Council, about the US response to ISIS and the efforts of American Muslims to respond to potential future threats. Echoes of Ferguson - As the leaders of Ferguson, Missouri start addressing the lessons of their community's violence, the experience of other cities may be helpful.

Stone Circles - Not just at Stonehenge in England, but all over the world, including the U.S., there may be evidence of pre-historic stone circles many think were used for religious reasons. Lucky Severson visited one such site recently found in Virginia's Shenendoah Valley.
