But didn't they probably try on September 11th to get the Congress, big time, by plane? After September 11th they would have had to use another route of attack.
Yes, that's what I meant by the jihadists go after the big time kills. When they do things, they don't nitpick with goofy letters that announce, "here we are, take penicillin, we've got anthrax". They'd send letters that say. "Oh what a wonderful show you have", and then throw a party when they're all dead. They also go for a much higher body count.
