Rapid City, South Dakota (CNN) -- Walid Shoebat had a blunt message for the roughly 300 South Dakota police officers and sheriff's deputies who gathered to hear him warn about the dangers of Islamic radicalism.
Terrorism and Islam are inseparable, he tells them. All U.S. mosques should be under scrutiny.
"All Islamic organizations in America should be the No. 1 enemy. All of them," he says.
It's a message Shoebat is selling based on his own background as a Palestinian-American convert to conservative Christianity. Born in the West Bank, the son of an American mother, he says he was a Palestinian Liberation Organization terrorist in his youth who helped firebomb an Israeli bank in Bethlehem and spent time in an Israeli jail. ...
But CNN reporters in the United States, Israel and the Palestinian territories found no evidence that would support that biography. Neither Shoebat nor his business partner provided any proof of Shoebat's involvement in terrorism, despite repeated requests.
