Frederick Douglass Moorefield Jr., a senior Defense Department official, and Mario D. Flythe have been arrested and charged with running a dogfighting ring in Maryland. The FBI and other agencies discovered veterinary steroids, weighted vests, collars and chains, and an apparatus used for electrocution at their homes. If convicted, they face up to five years in prison and a $250,000 fine, and the case has sparked outrage among animal rights activists.
