To quote Weird Al Yankovic's song White and Nerdy, "There's no killer app I haven't run" Lyrics . According to wikipedia this song was released September 26, 2006. This indicates to me the term app was commonly used more then three to four years ago as this song is filled with nothing but jokes related to nerds like "I'm fluent in Java Script as well as Klingon".

English translations of Arabic names are not exact. The name of Khalifa Abduallah will most likely be spelled differently by each individual who translates it. I have some experience doing Intelligence Analysis while in Iraq and I know there was work being done to standardize the naming conventions but it was far from complete or common practice.

From my experience I would search for that name utilizing some other variants and wildcards. Its been a few years but I would have have done something along the following lines (K*L*F) + (A*D*L*A) with constraints based on both separate words being within 15 characters or so. Some reports will have names in between or in different orders. The logic being that with each method of spelling it specific characters should remain constant. Khallifa, Kalifa, KhalIefa would all be picked up by the above search.

Here is a scenario for you.

It's 1 am and your mother goes into labor. Your father is not around because he was killed recently in a random act of violence. You get her into your beat up, barely functioning, pickup truck and start driving to the nearest hospital. As you round a corner you see an odd flash from a dark alleyway but don't pay any attention to it. Your focused on taking care of your hysteric mother. For your failure to stop a soldier in the dark alleyway opens up with a 240B Machine Guns.

Why didn't the soldiers have big flashing lights and large obvious signs that they were conducting an operation there? The soldiers were currently on a raid to capture a high level insurgent member who was personally responsible for importing and deploying EFPs.EFPs responsible for killing soldiers from their unit . The raid was being conducted as covertly as possible to minimize any early warning for the insurgents. This is also why the soldiers engaged with the minimal warning. The only people fleeing from soldiers conducting a raid at 1 am are most likely insurgents.

The end result was mother lived, baby died, son died. Insurgent was not captured. Did they deserve to be shot because the driver did not know that the ROE for the soldiers was to have signs visible (black out, no lights to see them with), verbal warning (could not be heard over engine), and to signal with a light to stop (a single flash of a light in the dense urban city in the middle of the nigth)? I'd say those are pretty ambiguous.

How do you determine the intent of the person who has entered your home? You present a range of responses that are acceptable based on the intent of the criminal. If you assume they are only trying to steal and it turns out they have broken in to kill your family you have now placed yourself at a severe disadvantage in a confrontation. If you assume that they have come in to kill your family and they are only trying to steal you put them at the disadvantage. Given the two options I would rather a criminal in my home be at the disadvantage.
