They are probably not terrorists, only sympathizers. The opinion I have from what I've been able to gather from various reports and posts last week and news clips of the bozos, what happened was:
1. they were laughing and joking in a diner on 9-12 about 9-11.
2. they made jokes about the grief we would feel on 9-13 for the new terror as it would be much greater than 9-11.
3. They may have felt they being "profiled" by the good citizens of Georgia as they were all of middle eastern appearance and one had some stupid embrioderied piece of laundry on his head, so
4. They embelished their story with talk which they knew would overheard such as "do you have enough to bring it down?" and " I have contacts who can supply us" and "they thought they were grieving on 9-11, wait untoil 9-13.
5. the lady Eunice who reported them has offered to take lie detector tests to back up that she is not a racist trying to go after the first A-Rabs she has ever seen passing through her town and was honestly concerned over what she heard.
6. The A-Rabs have refused to take a lie detector test.
Browse through the threads from last week, you will be able see all I have with more detail than I can provide with this reply and much more depending on how much time you have.
