Context: Operation Auxin was an Australian police operation in September 2004, leading to the arrest of almost 200 people on charges of child pornography.  These people were all accused of purchasing child pornography over the Internet, using their credit cards, from Belarusian crime syndicates, the credit card payments having been processed by a company named Landslide.com in Fort Lauderdale, Florida.  Among the accused were people holding positions of trust in the community, such as police officers (including one officer assigned to investigate child pornography), members of the military, teachers and ministers of religion.  Several of the suspects committed suicide.  It was the follow-up to the U.S. FBI operation Operation Falcon.

Tantiusques ("Tant-E-oos-kwiss") is a 57 acre open space reservation and historic site registered with the National Register of Historic Places.  The reservation is located in Sturbridge, Massachusetts, and is owned and managed by The Trustees of Reservations; it is notable for its historic, defunct graphite mines.  This is a rural area with much of the adjacent and surrounding area undeveloped and forested.  The reservation is entirely forested with oak-hickory forest and red maple in the wet areas and mountain laurel abundant throughout the understory.  The name "Tantiusques" comes from a Nipmuc word meaning “the place between two low hills."  The Nipmuc used the graphite to make ceremonial paints.  The property also contains the ruins of a 19th-century period house that belonged to a mine worker of mixed African American and Native American ancestry. Osborne v. Ohio, 495 U.S. 103 (1990) , is a U.S. Supreme Court case in which the Court held that the First Amendment allows states to outlaw the mere possession, as distinct from the distribution, of child pornography.  In so doing, the Court extended the holding of "New York v. Ferber", 458 U.S. 747 (1982) , which had upheld laws banning the distribution of child pornography against a similar First Amendment challenge, and distinguished "Stanley v. Georgia", 394 U.S. 557 (1969) , which had struck down a Georgia law forbidding the possession of pornography by adults in their own homes.  The Court also determined that the Ohio law at issue was not overbroad, relying on a narrowing interpretation of the law the Ohio Supreme Court had adopted in prior proceedings in the case.  However, because it was unclear whether the State had proved all the elements of the crime, the Court ordered a new trial.
