Well, it seems quite clear he was not a moslem, just a “regular” crazy evil person.
Right, and he wasn’t under the influence of some exotic, hypnotic drug, unless his psychiatrist prescribed something anti-psychotic... The question now remains - the two medical professionals who diagnosed him as unfit to fly, why did they give the ‘sick-notes’ to a man who was quite evidently mentally ill, why didn’t they inform the airline authorities?
Imagine a passenger with a diagnosis of ebola, he’s got his ‘sick-note’ and puts it in his pocket, and no one is any the wiser...
He was right in that prophecy he made to his girlfriend, his name will live for ever as one of the greatest mass-murdering scumbags that ever lived on the planet. I bet his parents are shattered.
