(AP) — An anti-Muslim militia group in Kansas calling itself "The Crusaders" first came to the government's attention when one of its members, alarmed by the heightening talk of violence, contacted FBI agents and became a confidential source, prosecutors said. The new details came Thursday in a government court filing in the case of three men accused of conspiring to detonate truck bombs at an apartment complex where 120 Somali immigrants live in the western Kansas meatpacking town of Garden City. The government's filing also documents an arsenal of firearms, ammunition, bomb-making materials and other items that were found during searches of the men's homes, vehicles and a storage unit.
