http://www.guardian.co.uk/usa/story/0,,2188086,00.htmlThe racial unrest in Jena, Louisiana, prompted by the hanging by white pupils of three nooses from a tree in the school playground has sparked a spate of similar incidents across America.
At least 10 cases have been reported in recent weeks of nooses being found in public buildings in chilling reminders of the country's deep-seated racial tensions.
In one case a noose was left dangling from the door of a black professor at Columbia University's teachers' college in New York. The professor, Madonna Constantine, a specialist in psychology and education, has written a book on race equality called Addressing Racism. Officers from the New York police hate crimes task force are investigating.
Susan Furhrman, the college president, said she deplored this "hateful act, which violates every ... societal norm."
The unrest in Jena culminated with a fight in the school after which six black teenagers, the so-called Jena six, were initially charged with attempted murder. The white pupils who put up the nooses were merely suspended for a few days.
