Describes two unpublished studies of child pornography offenders the author conducted within the Federal Bureau of Prisons Sex Offender Treatment Program. In the first (n=55) he found that 80% had committed contact sex offenses against children. In the second study (n=155) he found that 85% had committed contact offenses. Both studies relied on self report encouaged through treatment and coerced via polygraph examinations. Hernandez concluses that internet based child pornography offenders may be more dangerous than previously thought but cautions that he studied highly unique samples and that his methods were not rigourously scientific. Nonetheless, the second study was submitted to and accepted for publication in 2007 in the Journal of Family Violence. However, it was withdrawn at the last minute by the Author's employer, the Federal Bureau of Prisons.
