It's no lie. The 17th Citizens' Police Academy met for the second time at the Dalton Police Department on Tuesday night, and among the things they learned is the fact that it's not a good idea to try to fool a polygraph machine.
Officer Ken Brooks, who is one of the department's polygraph examiners and the recruiting officer, addressed the participants. While discussing the technical aspects of the polygraph equipment, he also sprinkled in several "war stories" about his time operating it. He included a story about an investigation where a man was suspected of carrying out a robbery. This man failed a polygraph test, but was later exonerated when someone else confessed to the crime. Afterwards, the examiner went back to the original suspect to ask why he'd failed the test so badly. Apparently, one of the questions in the polygraph exam was, "did you discuss with anyone else plans to rob the victim?" Well, as it turns out, the original suspect had, in fact, planned to commit a robbery. Someone else just beat him to the punch! So, while the polygraph isn't 100% reliable and not admissable in a court of law, Officer Brooks provided several other examples of the device's usefulness as a guide to investigators.
Participants also got a crash course on the role of the department's patrol division, and also the Situational Response Unit (SRU). The SRU is currently a two-officer unit that performs specialized patrol and investigation in different areas of the city. Among their responsibilities is investigating street-level drug sales and use.
Next week's Citizens' Police Academy class will focus on the department's Criminal Investigation Division (CID), with detectives teaching the group about their duties. The class will also focus specifically on the CID's gang investigators.
