Today’s global justice environment demands a new standard for collecting chemical, biological, and radiological criminal evidence in cases involving weapons of mass destruction. Recent criminal trials in Arusha, Tanzania (leaders of the Rwanda genocide), in The Hague (Slobodan Milosevic), in U.S. federal court (perpetrators of the U.S. embassy bombings in East Africa), and in a Scottish court sitting in the Netherlands (bombers of Pan Am flight 103, Lockerbie) all reflect a growing trend toward international prosecutions. In addition, the International Criminal Court, under United Nations auspices, was founded in 1998 and currently has 97 member states.
