Bioterrorism can be attacked from several different levels. This presents the public health perspective whereby the response begins at the finding of the first case. A complimentary view is that of law enforcement where prevention begins before any event takes place, in the 5 year period of preparation. This could be a simple as identifying people who want to take flying lessons but who do not want to learn how to land, or those purchasing Anthrax from web sites. Both of these approaches have to go hand and hand to prevent attacks.
