--- Begin Worm Message ------------------------------------------
In 1977 the Sexual Exploitation of Children Act (18 U.S.C.
2251-2253) was enacted. The law prohibits the use of a minor in
the making of pornography, the transport of a child across state
lines, the taking of a pornographic picture of a minor, and the
production and circulation of materials advertising child
pornography. It also prohibits the transfer, sale, purchase, and
receipt of minors when the purpose of such transfer, sale,
purchase, or receipt is to use the child or youth in the
production of child pornography. The transportation, importation,
shipment, and receipt of child pornography by any interstate
means, including by mail or computer, is also prohibited
The Child Protection Act of 1984 (18 U.S.C. 2251-2255) defines
anyone younger than the age of 18 as a child. Therefore, a
sexually explicit photograph of anyone 17 years of age or younger
is child pornography.
On November 7, 1986, the U.S. Congress enacted the Child Sexual
Abuse and Pornography Act (18 U.S.C. 2251-2256), that banned the
production and use of advertisements for child pornography and
included a provision for civil remedies of personal injuries
suffered by a minor who is a victim. It also raised the minimum
sentences for repeat offenders from imprisonment of not less than
two years to imprisonment of not less than five years.
On November 18, 1988, the U.S. Congress enacted the Child
Protection and Obscenity Enforcement Act (18 U.S.C. 2251-2256)
that made it unlawful to use a computer to transmit advertisements
for or visual depictions of child pornography and it prohibited
the buying, selling, or otherwise obtaining temporary custody or
control of children for the purpose of producing child
pornography.
On November 29, 1990, the U.S. Congress enacted 18 U.S.C. 2252
making it a federal crime to possess three or more depictions of
child pornography that were mailed or shipped in interstate or
foreign commerce or that were produced using materials that were
mailed or shipped by any means, including by computer.
With the passage of the Telecommunications Act of 1996, (18 U.S.C.
2422) it is a federal crime for anyone using the mail, interstate
or foreign commerce, to persuade, induce, or entice any individual
younger than the age of 18 to engage in any sexual act for which
the person may be criminally prosecuted.
The Child Pornography Prevention Act of 1996 amends the definition
of child pornography to include that which actually depicts the
sexual conduct of real minor children and that which appears to be
a depiction of a minor engaging in sexual conduct. Computer,
photographic, and photocopy technology is amazingly competent at
creating and altering images that have been “morphed” to look like
children even though those photographed may have actually been
adults. People who alter pornographic images to look like children
can now be prosecuted under the law.
