Sorry to over-orgasm your bubble. But that is a planned biological attack by U.S. authorities. It has their trademark tactics written all over. They are trying to commit genocide of minorities secretly but failed to do it secretly because the leaders are all idiots..........
It's because Amsterdam is below sea level. See, if they kill off the Dutch, there won't be anyone left who can understand that it could have been possible to protect New Orleans, and therefor the big conspiracy to kill off all black people in the US would be exposed. That's why Colin Powell isn't in the White House any more.
The attacks on the WTC were actually planned to occur at night, when they expected the cleaning staff (the majority of whom are black) to be there.
Since that isn't working, they're going to eliminate all blacks from the NFL; see Vick et al.
