Possessions of child pornography, and the distribution of it, are some of the most targeted activities for investigation by both federal and state law enforcement agencies. Of course, a person has to knowingly possess pornographic images of children to be guilty of possession, and the images have to be real (non-computer generated) images of underage persons (children) for a legitimate prosecution.

Practical problems some people encounter are learning of pornographic images that were loaded onto their sites without their knowledge, or certain images that were transferred without intent to distribute. These situations, in both pre-Indictment and post-Indictment stages, require the use of expert computer forensic services to establish facts that may not be known to investigators.

Both the United States Code (federal criminal laws) and the Texas Penal Code (state criminal laws) contain laws against possession of child pornography and distributing the same. Prosecutions under federal criminal laws can result in harsh sentences due to the existence of the United States Sentencing Guidelines (U.S.S.G.). The U.S.S.G. is a point system that is driven by the number of images that are the subject of the prosecution, as well as other related enhancements. Such enhancements could include the nature of the images and whether these were shared or distributed.

Title 18, United States Code, Section 2252 and 2252A, set forth the federal crimes regarding possession and/or trafficking of child pornography. Title 18, U.S.C. 2252A reads as follows:
