"Some descriptions of actresses in pornography have included attributes such as drug addiction, homelessness, poverty, desperation and being victims of sexual abuse," they said. "Some have made extreme assertions, such as claiming that all women in pornography were sexually abused as children. Stereotypes of those involved in adult entertainment have been used to support or condemn the industry and to justify political views on pornography, although the actual characteristics of actresses are unknown because no study on this group of women has been conducted."

A Massachusetts chemist accused of faking drug test results now finds herself in the same position as the accused drug dealers she testified against: charged with a crime and facing years in prison.

Annie Dookhan, 34, of Franklin, was arrested Friday in a burgeoning investigation that has already led to the shutdown of a state drug lab, the resignation of the state's public health commissioner and the potential upending of thousands of criminal cases.

"Annie Dookhan's alleged actions corrupted the integrity of the entire criminal justice system," state Attorney General Martha Coakley said during a news conference after Dookhan's arrest. "There are many victims as a result of this."

Dookhan faces more than 20 years in prison on charges of obstruction of justice and falsely pretending to hold a degree form a college or university.

Dookhan's alleged mishandling of drug samples prompted the shutdown of the Hinton State Laboratory Institute in Boston last month.

State police say Dookhan tested more than 60,000 drug samples involving 34,000 defendants during her nine years at the lab. Defense lawyers and prosecutors are scrambling to figure out how to deal with the fallout.
