I'm actually watching the documentary right now on tv
a very tragic day ....
I can't see how anyone could make a joke about something so tragic
Totaly agree with you it was awful
BUT the USA have done this to innocent people plenty of times over the last 60 plus years all over the world.
They always claim its sticking up for the underdog and people who have no rights in there own countries because of Dictatorships etc etc which is a load of crap , This goes on all over the world but where are the good guys(USA) to help ? well for a start there is nothing of interest $ wise for American business so of course you will never see them helping out in these types of countrys.
The amount of propaganda that Americans are filled with is quite numbing to the mind..
Over the last 9 years I have met quite a few Muslims from all over the world , now if I was to beleive like most do on this board all these people would be a ticking time bomb that want to take revenge on everything that is Western but they are not like that , they are friendly and open up there homes and extend there hands to you , if I was to beleive the christian fueled propaganda machine which americans are subjected to everyday these people are evil and the enemy but reality is a different picture..
Sure you did 
9 years later Bin Laden is still not caught, is ass raping US soldiers through his legacy via IED's
They shut down your entire country for 2 weeks and then continued to kill US soldiers in Iraq and Afghanistan, They are laughing at you.
Though I dont condone anything that took place on that day , all those innocent lifes taken for nothing you cannot stand back and think how brillient Bin Laden and his Circle are..
Billions and billions of $ is spent on the USA millatry and super advanced technolgy and look how basic there plan was and the damage and flow on it caused..
