JAKARTA - Forensic psychologist Reza Indragiri assesses that the police are excessive if they conclude whether or not the suspect is honest based on the results of thelie detector or a lie tester.

This assessment was submitted in response to the examination of the suspect in the murder case of Brigadier Nopriansyah Yosua Hutabarat or Brigadier J with alie detector. According to him, this tool only observes the reaction of the human body.

"It's really too much when the conclusion is to be honest or not honest, honest or lying. In my opinion, the durability of thelie detector is excessive," said Reza when contacted, Saturday, September 10.

Reza assessed that the police could find out the facts about an incident through the crime scene (TKP). A tool cannot simply become someone's honest or not.

He even called the use of lie detectors merely a theatrical act. "Try to show all of us, is there an absolute human physiological response, it cannot be denied that the response of people is lying. I'm sure the answer doesn't exist," he said.

"For example, the rising body temperature is a sign of lying. I said, if the person is sick, if it is hot, anxious, it will raise the body temperature," continued Reza.

Likewise with excessive sweat. He said this could not be a marker for someone lying, "It could be that person is sick. This person is just exercising or eating chili sauce," he said.

With this condition, he then considered that the tool could not compare the suspect's words with the reality of the shooting incident. Reza reminded thelie detectors only help the observation process.

"If there is an extreme physiological change, it is significant that it is considered a marker, maybe this person is lying," he said.

As previously reported, the National Police used alie detector to examine the suspects in the murder case of Brigadier J, including Inspector General Ferdy Sambo. On Friday, September 9, the former Head of the Propam Police Division was investigated using the tool.

However, the Head of the Public Relations Division of the National Police, Inspector General Dedi Prasetyo, did not say much about the examination. Likewise with the results of the test on Ferdy Sambo's wife, Putri Candrawati.

At that time, Dedi said that the examination using alie detector was a pro-justitia or fair legal step. So, the results are only for investigators.

In addition to the husband and wife, another suspect in this case, namely Bharada Richard target, Bripka Ricky Rizal, and Strong Maruf has also undergone an examination with alie detector. Unlike Ferdy and Putri, the three were declared honest and the results were submitted to the public.
