Whenever I watch reruns of "Friends" (which is every day!), I become very sad whenever the program cuts to a picture of New York City with the Twin Towers.
The way in which those 3,000 died is too horrible to even imagine.
No one has ever claimed that there is any justice in this life.
So probably we will never have the truth about 9/11.
Or maybe we do know the truth, but many people expect more.
I think there's a saying that goes something like this: "If you hear hoofbeats, think horses, not zebras."
