Over the past several decades, computers have become a principle means for storing personal, financial, and other information for large numbers of people. The significance of computers as a source of information suggests that access to computer records will become increasingly important in law enforcement. However, computerized records have several unique characteristics that are different from the physical evidence, and those unique characteristics have increased the difficulty in criminal activity's investigation and prosecution. In response, the Department of Justice in the United States have created numerous programs and deployed new technologies to aid in the investigation and prosecution of computer crime. Department of Justice's efforts to combat crimes that involved computer are centralized in its Computer Crime and Intellectual Property Section. The Section has published ”Prosecuting Computer Crimes” and ”Searching and Seizing Computers and Obtaining Electronic Evidence in Criminal Investigations” manuals to examine the federal laws that relate to computer crimes. In addition, courts and legal academics have been responding to this trend with increasing regularity, struggling to apply Fourth Amendment jurisprudence to the new contexts. Therefore, this article will examine legal issues related to search and seizure of computers and the preservation of computerized evidence.
