I remember a whole lot of people making fun of a lady in a Florida HoJo's restaurant who overheard ME types talking about terrorist plans. She reported it, they were arrested, and had the cover story of being "medical students" conveniently in the Bahamas, if I have the details right.
In fact, if I recall correctly, there were people on this forum who thought she was overreacting. I didn't, and still don't.
I think all of these incidents are test runs.

I still believe that lady to this day also. It never did smell right and I have thought once or twice about sending her a note to tell her so.
I remember that! I don't think she was over reacting either. My concern is that her experience will cause other people to remain silent out of fear of public ridicule. I don't believe this was a fluke innocent thing. This really concerns me.
