Description

Make sure your K9 investigation work holds up in court. Faulty K9 investigations often have serious consequences: the guilty might walk free, and the innocent might suffer. Internationally recognized dog handlers and trainers Dr. Resi Gerritsen and Ruud Haak use real-life case studies--historical and recent--to highlight K9 errors that can derail entire investigations. Each of these mistakes, such as influencing your dog's results or relying on contaminated scents, damages your reputation and the value of your work. But with the right knowledge and training protocols, you can minimize investigation errors.
K9 errors have hampered investigations from the earliest uses of dogs for police work in Europe to twenty-first century cases such as the 2001 anthrax attacks in the United States. Don’t let the same mistakes happen to you and your team.

Introduction
During te course of an investigation, searc-dog andlers ave been known to make mistakes. Sometimes tese are onest er-rors in judgement or te result of poor training—poorly trained andlers and/or dogs—but sometimes andlers deliberately per-petrate errors. Some of te most important reasons for investiga-tion errors include te andler’s: 1. lack of knowledge about influencing dogs, 2. lack of dog-training skills, 3. desire to ide te dog’s poor quality or caracteristics, 4. need to solve a case quickly, 5. interest in benefiting financially from a specific result, and 6. aspiration to appear to be a better dog andler tan oters.
In tis book we will consider at lengt errors and fraudulent practices committed by searc-dog andlers. We will present and discuss a variety of cases and causes of errors carried out during te course of scent-identification lineups, tracking, and mantrailing. Since tere is no international standard for scent-identification lineups, we’ve included a capter wit recommendations for just suc a standard. hese recommendations are based on te scientif-ically establised Dutc standard for scent-identification lineups.

We also describe te training for tis metod in detail. Since te beginning of te use of dogs for scent-identification lineups, tracking, and mantrailing, mistakes—bot unintended and in-tentional—ave detracted from te reputation of dogs and an-dlers in investigative work. In particular, andlers ave often been guilty of influencing teir dogs. To stress te significance of tis problem, we extensively discuss te conscious and unconscious influencing of te dog by its andler or by elpers, also called te Clever Hans Effect. Undetected errors in dog andling procedures lead to miscar-riages of justice, including prosecution and incarceration (even deat) of innocents, and tey are absolutely unforgivable. So we also include a capter devoted to ow dog andlers (and teir su-pervisors) can avoid making suc errors—deliberate or not—wit all kinds of searc dogs. Dr. Resi Gerritsen and Ruud Haak

ScentIdentification Lineups
“housands of Dutc police scent identification tests void,” read te eadlines of newspapers across te Neterlands in 2006. “All scent identification lineups wic took place from 1997 to 2006 by police dogs in te district Nort and East Neterlands may not be used anymore as evidence in criminal trials,” te Board of 1 Attorney General wrote in a letter to te public prosecutors. In October 2006, two police-dog andlers from te Nort and East Neterlands police unit admitted to te court of justice in te Dutc town of Leeuwarden tat tey did not always perform scent-identification lineups according to te rules. In several line-ups, te police-dog andlers said, te dog andler already knew were te suspect’s odor was located in te lineup. After tis ad-mission, te court immediately acquitted te suspects concerned, and te National Department of Criminal Investigation investi-gated eac member of te district’s team of seven police-dog an-dlers, wo were immediately removed from teir positions. Since April 2011, te Prosecutor’s Office in te Neterlands as not permitted te results of scent-identification tests as evi-dence in lawsuits. In a number of lawsuits, dog andlers ave ad-mitted tat tey made mistakes, prompting almost one undred convicts to request a review of judgments. he dogs ave been given oter duties.
