<p> In drug cases, &#8220;possession&#8221; is the fastest and surest way to prove a case. The actual drug has been seized, and its ingredients have been tested. The location where the drug was found and where it was possessed has been identified. At this point, the evidence is complete.</p>
<p> Simple possession is the simplest and easiest to establish as a crime, but in the case of Ryoko Yonekura (50), possession was not established.</p>
<p> Illegal drugs were seized from her home, and the results of an expert&#8217;s test were available. Despite this, the arrest could not be made. Why is that? Because the &#8220;presence of illegal drugs&#8221; and &#8220;who had control and management&#8221; of those drugs are two different issues.</p>
<p> Fumitaka Obinamaki, 52, a former police lieutenant of the Metropolitan Police Department, joined the agency in 1993. Since then, he has devoted most of his 30-year career to investigating organized crime, firearms, and drug cases. Having been on the front lines of major cases and having worked with a number of celebrities, Kobujimaki says he feels &#8220;nothing but discomfort&#8221; about the Yonekura drug scandal.</p>
<div data-friday-ad-slot="AD_inArticle"></div>
<p> Matri (Drug Enforcement Department, Kanto Shinetsu Health and Welfare Bureau, Ministry of Health, Labor, and Welfare) may have tried to cite him for joint possession, applying Article 60 &#8220;joint regular offense&#8221; of the Penal Code, but that is more difficult to prove than single possession. It is not enough to say, &#8220;There were drugs in the room where we lived together.&#8221; A reasonable explanation of &#8220;joint control and management of drugs&#8221; is needed.</p>
<p> The case was dead in the water when we could not get a statement from the Argentinean national, who is said to be Ms. Yonekura&#8217;s lover, and we could not cross-check it with physical evidence. Even if Ms. Yonekura was arrested, there was no prospect of being able to prove joint possession in a subsequent enhanced investigation.</p>
<p> Still, there was the fact that illegal drugs had left the room. The case must be closed. After repeated discussions between Matri and the public prosecutor&#8217;s office, the drop-off point was probably &#8220;sending the case to the public prosecutor&#8217;s office.</p>
<div data-friday-ad-slot="AD_inArticle"></div>
<p> Because of the social repercussions, the Metropolitan Police Department headquarters basically takes action in celebrity drug cases. A group of specialists who specialize in this field handle the investigation.</p>
<p> In our terminology, we call it &#8220;getting a sense&#8221; that the investigation will lead to a level of 95% &#8230;&#8230; or even more. We have to get the evidence to the level of &#8220;98% guilty&#8221; before we can make an arrest. Otherwise, we end up &#8220;just picking on the celebrity&#8221;.</p>
<p> In fact, Mr. Yonekura was not indicted, but his TV commercials have been stopped. It is not easy for TV stations to use her in dramas in front of sponsors.</p>
<p> The image of a celebrity is important. You could say it is their life. That is why we must be very careful and exhaustive in our investigations of celebrity matters.</p>
<p> The beginning of an investigation may vary from a story, a tip, or just a rumor, but the process is the same: steadily accumulating evidence and leading to an arrest. In the case of the arrest of a major artist, &#8220;the way he parked his car was the key.</p>

<h2> What is the shocking fact that the industry term &#8220;shabu stop&#8221; means?</h2>
<p> Every day, while monitoring the target&#8217;s behavior, checking his color or checking where he stops, there is a moment when you say to yourself, &#8220;I&#8217;m not done! There are moments when the target&#8217;s behavior clearly changes. There are times when the target&#8217;s behavior clearly changes.</p>
<p> There is a term in our industry for this: &#8220;shabu stop. It is a way of stopping a car that is unique to people who have used methamphetamines, but on the day when I felt that the behavior was different from usual, the artist stopped the car.</p>
<p> I can&#8217;t go into specifics because it would affect the investigation, but it was definitely a stop that would cause problems for the cars following us. I heard that people in the Motor Vehicle Patrol Unit see this from time to time, but even though I had heard about it, that was the first time I saw it.</p>
<div data-friday-ad-slot="AD_inArticle"></div>
<p> Since then, I have seen a car parked in a shabu-shabu area several times and questioned it, but it still tested positive for methamphetamine. Drug ingredients were also clearly detected in the car of a major artist.</p>
<p> The artist in question was arrested, making headlines that rocked the world. On the other hand, there was also a case in which a major celebrity was missed due to human error, although the evidence was solidified and a raid was carried out.</p>
<p> It was not my field, but when conducting a urine test on a suspect, whether out of concern for privacy or because I was put off by the other party, I let the suspect collect urine alone in a restroom and was unable to prove &#8220;whether the urine was really the suspect&#8217;s urine or not.</p>
<p> The police station in charge was blamed because it was the police station that arrested the big-name celebrity, but I was told that an investigator who came from elsewhere to support the police station was in charge of the case. In other words, it was not the jurisdiction&#8217;s mistake.</p>
<p> I understand that there is a human rights violation aspect to observing a suspect urinate in the field. I understand that it is not recommended from a textbook standpoint, but if the evidence is destroyed because of it, it&#8217;s a real mistake. You thought, &#8220;This is the mistake of someone who doesn&#8217;t know the scene.&#8221;</p>
<p> If you don&#8217;t check the area where the urine is collected, it could be replaced with tea or someone else&#8217;s urine. In fact, I once interrogated a yakuza who was carrying someone else&#8217;s urine in a condom.</p>
<p> The yakuza was arrested after a urine test after I found the hidden urine, but when I tested the urine in the condom as a trial, I got a positive result from that as well. When a yakuza is taken to the police station for a drug case, his friends sometimes secretly let him carry a condom filled with someone else&#8217;s urine.</p>
<div data-friday-ad-slot="AD_inArticle"></div>
<p> I digress, but the place to collect urine does not have to be the toilet in the suspect&#8217;s home. I would have said, &#8220;I&#8217;m sorry, but you&#8217;ll have to come to the station. If I did it at the station, there would be no room for deception.</p>
<p> The popular singer, who would later be arrested several times for drug-related offenses, says that the investigation began when her boyfriend was caught in the line of duty.</p>
<p> When we interviewed him in the interrogation room, we found out that his relationship with the singer was not going well. Apparently, the singer had another steady boyfriend, and as I asked him about his various problems, he told me, &#8220;He&#8217;s on drugs, too. Well, that&#8217;s no fun for a boyfriend. Not only did he make another man, but he was the only one who got caught.</p>
