You know how it goes: Right before Horatio Caine puts on his sunglasses and throws off a corny one-liner as the The Who screams, the forensics team is looking at a blood splatter on the wall and determining that it was a gunshot wound from close range by a six-foot tall, left handed shooter who wore sandals and had a limp.Far fetched?
