I'll point out that a lot of Freepers on the "live" thread last night while this situation was unfolding were insisting that the guy was a Muslim -- but I don't think a single person thought he was from Turkey. Most folks seemed to think he was Pakistani.
I'm not an expert on ethnicities, but I think I'd have an easier time differentiating a Pakistani from a Turk than a Turk from a Hispanic.
Someone guessed Armenian among other things.
It depends on your personal experience. If you live in the region, it is easier to make such distinctions.
That’s like trying to tell the difference between the africans.....there are distinctions but unless you’re familiar with their tribes it’s not always easy to discern...same with s.americans....
