Force hundreds of people to be imprisoned against their will, and injected with potentially lethal antibiotics, with one simple 25 cent phone call. ----- LOS ANGELES (AP) -- Ninety-one people were held for almost eight hours as a health precaution after an anonymous threat claimed anthrax had been released into the air ducts of a federal building. The people were given antibiotics and special suits to wear over their clothes Friday before preliminary tests showed none of them had been infected with the potentially deadly bacterium. Authorities held the people, most of them U.S. Bankruptcy Court staff members, as firefighters and FBI investigators tested the ventilation system for anthrax spores. Those tests also came up empty, said Jonathan Fielding, spokesman for the Los Angeles County Health Department. The FBI would not release details of how the threat was delivered. -- Eric Michael Cordian 0+ O:.T:.O:. Mathematical Munitions Division "Do What Thou Wilt Shall Be The Whole Of The Law"
