I really doubt that she was yelling 'Allahu Akbar'.
1. This was only mentioned by one witness in one article that didn't seem to be a reliable source.
2. Other witnesses mentioned the loud noise of the engine being gunned. It seems unlikely that anyone would have been able to hear accurately what she was saying through the window and over the sound of the engine as the car drove by and they were dodging out of the way.
3. There has been no other information about her past that even mentions her being Muslim or an extremist or speaking Arabic.
Something very similar to this happened in in 1980. The perpetrator was just nuts.
Just because you want something to be true doesn't mean that it is.
Actually people on Free Republic were listening to police scanners and it was reported 3 different people heard her yell Allahu Akbar according to police scanner .
so WHY did she do it?...deliberately.....you say its not allah acne but then WHAT is the reason?
