There seems to be considerable evidence that many members of the Muslim community knew in advance of the attack. My wife works in an office building and a Muslim co-worker sits behind her. The Muslim lady rarely misses work and she was there on 9-10 and 9-12, but absent on 9-11. When asked why she missed work she said she had something to do. I wonder how common this is for Muslims working in office buildings
Isn't this just a coincidence?
