At the scene? Who said anything about being at the scene? The hospital that the victims of said attack would be taken to does not count?
B/C it makes no sense that people wouldn't be taken to a hospital in the event of serious injury resulting from a terrorist attack, I will use a hospital setting for this example.
Given that 10% of doctors in America are Muslim, one can assume that they have a 10% chance of having a Muslim doctor when taken to the ER, this is sheer chance b/c (in my experience) you do not choose where the ambulance takes you, or the doctors that treat you upon arrival. During my last trip to the ER (for a car accident in which my vehicle was struck from behind by a drunk driver) I was treated by 3 doctors and 3 nurses (Standard ER doc, Ortho doc and Neuro doc). That's 3 out of 10 or a 30% chance to be treated by a Muslim doctor.
Yes, I am aware that my experience differs from that of a terror victim (they would most likely see more than 3 doctors while hospitalized).
