The purpose of this document is to develop a basic understanding of key technical and legal factors regarding searching and seizing electronic storage devices and media. As computers and related storage and communication devices proliferate in our society, so does the use of those devices in conducting criminal activities. Technology is employed by criminals as a means of communication, a tool for theft and extortion, and a repository to hide incriminating evidence or contraband materials. Law enforcement officers must possess up-to-date knowledge and equipment to effectively investigate today's criminal activity. The law enforcement community is challenged by the task of identifying, investigating and prosecuting individuals and organizations that use these and other emerging technologies to support their illicit operations.
