Well said, GrannyGravy13.
It was not just plagiarism, his whole life story was constructed on fantasy and lies, most of which could easily have been disproved. Any student who questioned his ability as a lecturer at various universities was immediately shut down by accusations of racism.
What has happened as a consequence is very tragic but he obviously could not face the shame.
Had anyone had the courage to investigate him much earlier this may never have ended in tragedy.
There have been failures all round.
