Feds: Radical Islam group leader killed in raid

DETROIT - A leader of a radical U.S. Sunni Islam group killed in a shootout with federal agents near Detroit repeatedly told followers that the government was the enemy and they must be willing to take on the FBI — even if it meant death, authorities said.

“You cannot have a nonviolent revolution,” Luqman Ameen Abdullah said, according to a 2008 conversation secretly recorded by a confidential FBI source.

…The FBI said Abdullah, also known as Christopher Thomas, was an imam, or prayer leader, of a radical group named Ummah whose primary mission is to establish an Islamic state within the U.S.

Abdullah told followers that it was their “duty to oppose the FBI and the government and it does not matter if they die” and to “simply shoot a cop in the head” if they wanted the officer’s bulletproof vest, Leone wrote.

The affidavit also said bombs, guns and even the recipe for TNT were among Abdullah’s regular topics with his allies. Group members and former members said they were “willing to do anything Abdullah instructs and/or preaches, even including criminal conduct and acts of violence,” the FBI agent wrote.

Of course CAIR tries to make the imam look like a boy scout.

But that description doesn’t match what Dawud Walid, executive director of the Council on American-Islamic Relations’ Michigan chapter, said he knew of Abdullah.

“He would open up the mosque to homeless people. He used to run a soup kitchen and feed indigent people,” Walid said. “I knew nothing of him that was related to any nefarious or criminal behavior.”
