“The U.S. Sentencing Commission has issued a report, The History of Child Pornography Guidelines, as a first step in its review of the punishment prescribed for the sexual exploitation of children…The Commission has sought to implement congressional intent in the area of child pornography offenses in a manner consistent with the SRA and subsequent legislation. As discussed in this paper, in amending the child pornography guidelines over the years, the Commission has reviewed sentencing data, considered public comment on proposed amendments, conducted public hearings on proposed amendments, studied relevant literature, and considered pertinent legislative history.”
