1. AUSTRALIA HOSTAGE INVESTIGATION
Why?: Lots of questions remain in the aftermath of yesterday's hostage siege in Sydney. Australian Prime Minister Tony Abbott said, "It will take time to clarify exactly what happened." Dead is the gunman, Man Haron Monis, and two hostages. What did the gunman want? Why did he choose the Lindt Chocolate Café as his target? We may never know. Up to 17 people were held at one point before some escaped and police stormed in. Authorities describe Monis as a self-styled Muslim cleric, who was well-known to police and who had embraced a radical Sunni theology.
