Did disabled man consent to sex with 'prof' who helped him type?

There is a fascinating and harrowing account in this weekend's New York Times Magazine about a relationship between a professor and a severely disabled man.

The man, known as D.J., has severe cerebral palsy, doesn't speak, and has been diagnosed with a significant intellectual disability.

The professor, Anna Stubblefield, was formerly chair of philosophy at Rutgers University. She'd been asked by D.J.'s family to help him communicate through a method known as "facilitated communication," where someone supports the arm of a person to enable them to type. Much controversy surrounds the use of assisted keyboarding and whether the messages are generated by the facilitator, or the person being supported.

Anna was charged with, and found guilty of, two counts of first-degree aggravated sexual assault and now faces up to 40 years in prison. She said they were in love.
