A day after killing Trayvon Martin, George Zimmerman passed a police lie detector test when asked if he confronted the teenager and whether he feared for his life ‘when you shot the guy,’ according to documents released today by Florida prosecutors.
According to a ‘confidential report’ prepared by the Sanford Police Department, Zimmerman, 28, willingly submitted to a computer voice stress analyzer (CVSA) ‘truth verification’ on February 27. Investigators concluded that he “has told substantially the complete truth in regards to this examination.”
Zimmerman, the report noted, ‘was classified as No Deception Indicated (NDI).’
WOW! Doesn’t this new information change everything? Not quite. Back on April 23, this scruffy little blog—Stately McDaniel Manor—not only wrote about that very topic, but explained—in Update 3—in considerable detail the two types of “lie detectors” and precisely why the results of Zimmerman’s examination will not be admissible in court. The section of that update dealing with lie detectors began:
One bit of evidence that will not be presented in any hearing or trial is the voice stress examination Zimmerman underwent, and passed, during the initial investigation phase conducted by the Sanford Police. However, the results of that test, even the fact that it was given, will not be allowed at trial. Why not? Zimmerman’s attorney would surely like that to be introduced as evidence.
In that same update, lo and behold, I also noted that Zimmerman reenacted the incident for the Sanford Police that morning. I ended the section on lie detectors with this paragraph:
Competent, professional investigators know that the primary value of this technology is in maneuvering criminals into confessions. Still, they also know that in any case, there are some things they can never know with absolute certainty—and they hate uncertainty. Good investigators like to know; they like certainty. They like to be able to wrap up each investigation in a complete, neat and unassailable package with every detail properly categorized and every duck in its proper row. They dislike any doubt, any unknown. If they are truly professionals, they don’t want to charge innocent people with crimes they didn’t commit. Or at the very least, having a polygraph or VSA confirm what they already believe can help them sleep a little more easily. No doubt the Sanford police slept well after the VSA confirmed what their investigation revealed. However, all police officers know that the technology is nothing more than an investigative tool. The danger is that they, and their supervisors, can come to rely upon it rather than spending the time and effort necessary to properly do their jobs, time and effort that can be rather tedious and that will almost always leave some things uncertain.
If you haven’t seen Update 3 or would simply like a quick refresher on the technology, by all means, take the link.
In any case, I do take some small pleasure in trying to be first with solid analysis. It would appear in this case that I was. I’m not picking on anyone mentioning this information, and certainly not the influential Instapundit–bless their little hearts—but once again, this is old news to readers of SMM. As always, thanks for your support!
