BBC:

A teacher in the US state of Georgia has been suspended after allowing students to dress in mock Ku Klux Klan robes for a project.

The teacher had asked four students, none of whom were black, to re-enact scenes from history for a class film.

Officials said the teacher had used poor judgement. Georgia has a history of violent racial tension and students and parents were upset by the incident.

The teacher, who is white, acknowledged it was a mistake to film the scene.

And if one of the students had been black?
