It’s not merely the extent of most crime show analyses, but also the technology and ease with which investigators use it that’s questionable. Here, the technician simply inputs the algorithms into a computer program, and poof, she’s got her 3D reconstruction. In other cases, it’s DNA samples, which returned from the lab within hours as opposed to weeks. Then there’s footage—crime scene investigators seem to be able to take the blurriest footage and blow it up to reveal crucial details. Like the faint impression of the killer—holding a gun, no less—in a window.
