He wasn't headed for SFO.
It has been postulated that Muslims are psychologically unstable, due in large part to genetic factors. These people, especially Arab Muslims, have been inbreeding for millenia. They usually marry within their own clan, and hardly ever outside their tribal unit. The influx of oil money beginning in the 1960's only made it worse.
For example: Osama bin Laden, is one of 75 children born to a Yemeni sequentially married to at least 30 cousins, many of them actually sisters. Osama has fathered upwards of 70 children of unions with perhaps 25 or 30 of his cousins, many of them sisters.
Check out ObL physically. Tall, gangly, prognathous features, deaf, poor eyesight, kidney problems, and bonkers. This guy could walk down any street in Riyadh and no one would give him a second glance. Since he can walk and talk, the Saudis probably consider HIS birth defects minimal! Sorry, whenever one deals with an Arab, it might help one to remember that the Arab is the product of hundreds of generations of what we westerners might reasonably consider medically dangerous incestuous inbreeding. Even if an Arab appears reasonably normal in the physical sense, he might very well be a mental case. Worse, these in-breeding habits have led to a huge population increase in Arab countries since the '60s. E.G. Saudi Arabia QUINTUPLED it's population, leaving a surfeit of very ignorant young men, many of them displaying the endemic mental (and physical)problems, with absolutely nothing to do except hang around the mosques, train as terrorists and fantasize of stepping into a dynamite jockstrap to qualify for their 72 virgins.
I bet you my finest camel that young Mohammed Ghanem was going home to marry his cousin. I bet you my finest Arabian stallion that this stud was also eventually going to marry her sister. A flock of my goats says his parents are cousins. I also bet you that young Mohammed is nuttier than a fruitcake.
Why else would he bring a knife to a night flight?
