Someone's got a sense of humor.

If you go onto Facebook and start searching on the names of the Dubai assassins, you'll see that most of them have a Facebook page.

Obviously this was done as a joke.

But what this really means is that in the future spies are going to have to create even better background cover identities, because Dubai is going to hook up their passport control to compare their photos on Facebook and simply try to see if they exist in the online/real world.
