Hi Noia

are they acctualy speaking a real language? I would say it was a prank on the shop owners (best demonstrated in vid 2), seems like a stitch up to me...
My guess would be Parsee, followed by Arabic. I would say that it is real, just check out the background, it is not a shop it is a CSI ballistics lab (notice safety glass screens and remote camera on tripod.

Also note the untidiness of the desk to the left of the shooter..............that tells me it is real............all TV forensics labs are spotless.

Can't quite make out the gun. It obviously has a notch and post sighting mechanism, and it has a bolt action. I would guess something like a .458 Winchester or a .460 Wetherby?
