Excerpt:
The Justice Department has opened an investigation into an F.B.I. raid near Detroit last fall that left a Muslim prayer leader dead with 21 gunshot wounds, officials said Tuesday.
The prayer leader, Luqman Ameen Abdullah, 53, had been described in court papers as a separatist Muslim intent on overthrowing the United States government, and as someone whom counterterrorism agents had been following for years.
Mr. Abdullah, however, had not been charged with a crime when he was killed in a shootout in late October inside a warehouse where he stored goods in Dearborn, Mich. F.B.I. agents said that they had intended to arrest him on charges that included conspiracy to sell stolen goods and the illegal possession of firearms, but said that he had opened fire, killing an F.B.I. dog.
