By the way, http://en.wikipedia.org/wiki/List_of_notable_aircraft_hijackings [wikipedia.org] is why we don't profile for one race / religion.
Why not ?
With the exception of one Cuban (I'm guessing not Muslim), one Filipino (50:50), and one who gave himself up in Israel (not Muslim unless also batshit crazy), EVERY other notable hijack in the 2000's HAS been by people of the Islamic faith who demanded safe passage to a Muslim country.
That's 13 on 16 mate, over 81%
Every other religion condemns the acts of it's militant elements and would probably never do anything similar. Islam is at it's core a religion founded on militant behaviour, and it's adherents are called upon to respect Fatwahs. With that mentality, isn't it better to be safe than sorry
Imagine Russian Roulette with every chamber loaded, except most of them are loaded with blanks. Would you pull the trigger ?
