"The Internet, computer networks, and automated data systems present an enormous new opportunity for committing criminal activity. Computers and other electronic devices are being used increasingly to commit, enable, or support crimes perpetrated against persons, organizations, or property. Whether the crime involves attacks against computer systems, the information they contain, or more traditional crimes such as murder, money laundering, trafficking, or fraud, electronic evidence increasingly is involved. It is no surprise that law enforcement and criminal justice officials are being overwhelmed by the volume of investigations and prosecutions that involve electronic evidence. To assist State and local law enforcement agencies and prosecutorial offices with the growing volume of electronic crime, a series of reference guides regarding practices, procedures, and decisionmaking processes for investigating electronic crime is being prepared by technical working groups of practitioners and subject matter experts who are knowledgeable about electronic crime. The practitioners and experts are from Federal, State, and local law enforcement agencies; criminal justice agencies; offices of prosecutors and district attorneys general; and academic, commercial, and professional organizations. The series of guides will address the investigation process from the crime scene first responder, to the laboratory, to the courtroom. […] Due to the rapidly changing nature of electronic and computer technologies and of electronic crime, efforts will be periodically undertaken to update the information contained within each of the guides."
