Polygraphs & Lie Detectors in Florida Courts

“In law school and on the street everyone knows that lie detectors are not admissible in court. Wrong!”

A crew member of a ship claimed he did not know drugs were on board the ship. He was indicted in the Middle District of Florida’s Tampa Division. They indict them all, let the jury sort them out indictment charged many aboard with knowing the ship had drugs on board. This is not a rare claim where smugglers tend to minimize the need to know that 10-100 million dollars of cocaine is on board the vessel. Judge says let them use the polygraph. The best way to understand the polygraph case is to read it here.

Federal Criminal Defense Attorney Court Ruling on Polygraph

Update – Comments from Lead Defense Counsel

“There were three important lessons learned from this experience: 1) it is important to have the testimony of a qualified scientist, such as Dr. David Raskin, to testify in the Daubert hearing as the polygraph examiners are usually not well-versed enough in the scientific studies supporting the technique; 2) using a highly qualified examiner with extensive prior government experience is also critical, and 3) the relevant questions must be simple enough but carefully constructed so the results of the exam are indisputably meaningful.”

“[I]it helped to submit Dr. Raskin’s declaration in advance of the Daubert hearing so that all of the detailed support for the polygraph’s admissibility was on the record in advance, making the actual hearing go much more smoothly.”

Polygraph Case Excerpts:

“Defendant Angulo-Mosquera plans to testify in his own defense at trial and requests that the results of the polygraph examination be admitted into evidence to corroborate his testimony. The Government objects arguing that polygraph examinations are just “one step above” junkscience and are “not suitable for juror consumption.” TR at 46:15-24, 49:16-17. The results of the polygraph examination, if admitted at trial, would be presented through expert witness testimony.”

“[T]the Court held an evidentiary hearing to determine the admissibility of the polygraph evidence and expert testimony regarding same, under Federal Rule of Evidence 702 (“Rule 702”) and Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993). At the hearing, Defendant Angulo-Mosquera presented the testimony of Dr. David C. Raskin, who for 44 years has conducted laboratory and field research on polygraph techniques for the detection of deception, taught university courses about polygraph techniques, trained government and lawenforcement polygraph examiners, and published extensively on polygraph techniques, regardingthe reliability of polygraph examinations in general and the examination in this case specifically.”

Junk Science Claim

“Defendant Angulo-Mosquera plans to testify in his own defense at trial and requests thatthe results of the polygraph examination be admitted into evidence to corroborate his testimony.The Government objects arguing that polygraph examinations are just “one step above” junk scienceand are “not suitable for juror consumption.” TR at 46:15-24, 49:16-17. The results of thepolygraph examination, if admitted at trial, would be presented through expert witness testimony.”

“Thus, in determining the admissibility of expert testimony under Rule 702, courts mustengage in a rigorous three-part inquiry, determining whether:(1) the expert is qualified to testify competently regarding the matters he intends toaddress; (2) the methodology by which the expert reaches his conclusions issufficiently reliable as determined by the sort of inquiry mandated in Daubert; and(3) the testimony assists the trier of fact, through the application of scientific,technical, or specialized expertise, to understand the evidence or to determine a factin issue.”

“Some factors that bear on this inquiry are:1) whether the expert’s theories, methods or techniques can be or have beentested;2) whether the technique, method, or theory has been subject to peer reviewand publications;3) whether the known or potential rate of error of the technique when appliedis acceptable; and4) whether the technique, method, or theory has been generally accepted inthe scientific community.”

Polygraph Ruling

“Thus, the Court finds the polygraph evidence to be admissible at trial to either impeach orcorroborate witness testimony. Further specifics regarding the admission of the polygraphevidence will be determined at the time of trial. Accordingly, it is herebyORDERED that Defendant’s Motion for an Evidentiary Hearing on Admission ofPolygraph Evidence (Doc. 67), construed as a motion to determine the admissibility of thepolygraph evidence under Federal Rule of Evidence 702, is GRANTED. The Defendant maypresent the polygraph evidence, through expert testimony, to corroborate or impeach witnesstestimony at the trial in this matter.”
