DETROIT – Federal agents investigating what they describe as a Christian militia bent on violence against police seized suspected crack cocaine and steroids, weapons, gas masks and a book of Adolf Hitler's speeches during raids of members' homes last month, according to search warrant records. The raids were conducted over a 4 1/2-hour span in Michigan, Ohio and Indiana on the night of March 27. Authorities recovered hand grenade instructions and schematics, a container of potassium chlorate and other items during a raid that night at the southern Michigan home of David Stone, the suspected leader of the Hutaree.
