Some say it's the Columbians who threatened the U.S. for taking that drug lord. They said the U.S. would be sorry for doing that. Others say it's Osama Bin Lauden... who knows. This is truely a tragedy and horror story for those who died and survived this hateful act. I heard people were jumping out of the WTC to their death, it was either die of smoke, fire, or you jump. Who knows how many people have died. Bush has got to do something.
