28 CFR 23.2: Background.

It is recognized that certain criminal activities including but not limited to loan sharking, drug trafficking, trafficking in stolen property, gambling, extortion, smuggling, bribery, and corruption of public officials often involve some degree of regular coordination and permanent organization involving a large number of participants over a broad geographical area. The exposure of such ongoing networks of criminal activity can be aided by the pooling of information about such activities. However, because the collection and exchange of intelligence data necessary to support control of serious criminal activity may represent potential threats to the privacy of individuals to whom such data relates, policy guidelines for Federally funded projects are required.
