Barton Gellman Leads Quotations

First developed as a weapon by the U.S. Army, VX is an oily, odorless and tasteless liquid that kills on contact with the skin or when inhaled in aerosol form. Like other nerve agents, it is treatable in the first minutes after exposure but otherwise leads swiftly to fatal convulsions and respiratory failure.

On average, since 9/11, the FBI reckons that just over 100,000 terrorism leads each year have come over the transom. Analysts and agents designate them as immediate, priority or routine, but the bureau says every one is covered.
