One of the things that seems to go by most people is that the Israelis could be Palestinians. Traveling on a pasport issued by Israel could be a number of Arab Palestinians.
Considering the folks stopped after the WTC and the Whidbey Island stop, I would like more information on the "ethnicity" of the people stopped, before I give the "all clear" signal.
Good point.
The 5 WTC 'folks' were confirmed to be jewish israelis.
