I think they have something planned. They seem to like symbolism, and what better day to plan something than on the birthday of America. Hopefully we're on to them, though. They took us by surprise on 9/11 - but everybody is waiting for them this time, there are millions of eyes and ears looking for them. God Bless America.
The fact that we are running around as 'headless chickens' right now...is terrorism in its own right. Why waste resources while we (USA) are burning plenty?
