A lawsuit has been launched against a school teacher who showed Brokeback Mountain to a class of young students. Twelve-year-old Jessica Turner and her grandparents, Kenneth and LaVerne Richardson, are seeking $500,000 against the Chicago Board of Education after the movie was shown at Ashburn Community Elementary School. The lawsuit, filed in Cook County Circuit Court on Friday claims Turner "suffered psychological distress" after viewing the R-rated film, which was viewed by the class without permission from the student's parents or legal guardians. Turner's grandfather Kenneth Richardson, who complained to school heads in 2005 over profanities in educational reading literature, says, "The teacher knew she was not supposed to do this. It is very important to me that my children not be exposed to this. This was the last straw. I feel the lawsuit was necessary because of the warning I had already given them on the literature they were giving out to children to read. I told them it was against our faith." R-ratings denote the film in question contains one or more adult themes - adult language, strong sexuality, nudity, violence or drug use.
