Sheriff John Carter of Wayne County, Georgia, received a hot tip in February last year that he remembers well. The caller said he had reason to believe the Muslims of America, a mysterious Islamic commune with cult-like devotion to a radical Pakistani sheikh, was building underground bunkers on its land near the tiny town of Jesup. He immediately paid a visit to the reclusive Muslim group’s compound, where Mecca Circle turns off of Oreo Road several miles north town. About 38 people live in the commune, where women wear burqas and the men don the skullcap common among Sufi Muslims.
