“Splitting Fibers”
Monday, February 28th, 2005When I first became interested in forensics, I loved to watch the Discovery Channel and Learning Channel shows about real-life crimes and the evidence and techniques that were used to solve them. I can only assume that these shows are created by PBS-type production companies rather than by the Hollywood studios that generate crime dramas. Still, I address them here because the documentary style shows can be just as misleading as Hollywood dramas.
This misrepresentation is the main reason I’ve gotten away from watching even the more factually based shows. I suppose part of my disdain for them comes from playing my part in the investigative process day in and day out. Most of these shows contain a synopsis of anywhere from one to three cases packaging months or years of investigative work into a segment no longer than a “Spongebob Squarepants” cartoon. As such, these segments are typically only able to focus on one particular aspect of a case and ignore the bulk of the investigation.
An example would be a case in which a suspect was identified because a single fiber found on the victim matched a rare imported rug that was recovered from the suspect’s home. Granted, this particular piece of evidence may have been the element of the case that ultimately solidified the guilt of the suspect. In my opinion, many shows give the impression that the entire case was based on the importance of one piece of evidence and the comparative analysis of one fiber expert.
In actuality, dozens of people and hundreds of articles of evidence have played a part in any given case. The example given above gives due credit to the fiber expert’s work, but completely ignores the very likely possibility that some other person was proficient enough in their role to have discovered the fiber on the victim and collected it in the first place.
Editorial Comments:
–I’m hesitant to say that it isn’t possible for one piece of evidence in a case to outweigh all the rest. Doing so would completely ignore the exculpating effect of O.J. Simpson “struggling” to put on a pair of gloves in the minds of jurors when it came time for them to evaluate actual evidence.
–I’m not trying to discount the role of the fiber expert. As a matter of fact, I admire their ability to do what they do.
