.The guy who owned/leased the twin tower world trade center (Larry silverstein) took terrorist insurance 3 months before 9/11 attack.
Not a normal insurance but a terrorist insurance !!!
Further more he had an odiesity to ask for 2 compensation as he was claiming that it was two separate terror incidents.
However the court rejected his claim and gave him one claim sum of $4.5billion.
Innocent life's were lost that day , all for what.
Follow the money and you will definitely find the real culprit.
