THE New Year's Eve carnage in New Orleans that left at least 15 revelers dead focuses new light on the possible resurgence of the Islamic State of Iraq and Syria, or IS, the terrorist organization that built its notoriety on the horrific video-taped execution of its captives.Investigators said they have found an IS flag in the pickup truck the 42-year-old man used to plow into a huge crowd on Bourbon Street.
