Was interpreter a security risk?

The sign language interpreter at Nelson Mandela's memorial, who has been called a "fraud" around the world for allegedly making up gibberish, is now blaming the incident on a schizophrenic hallucination.

Thamsanqa Jantjie told the Associated Press he saw visions of angels flying into the stadium during the event, and that he's had a history of violent incidents in the past.

But in a separate interview with our David McKenzie, Jantjie defended his performance and claimed that his schizophrenia was his inspiration for wanting to become an interpreter.

One of the big questions now is: was Jantjie a security risk to President Obama and all of the foreign dignitaries that attended the service?
