His trading was likely not categorized as an insider trading, meaning his action was likely legal, as far as I know. However, if there is an information to gain a return without fail, there should be someone breaching a law. This information has been an illegal insider in nature and some of them had definitely known its true identity.
The e-mail sent to me was a leading clue to the real crime and the investigators might have found authentic problems.
I assumed that way he was driven to a suicide, probably by the electromagnetic wave. He should have gotten more proofs as he got this type of information more frequently and might have known a true nature of this circle as he was totally connected to the investment community. Even if he did not commit any crimes, there was a high probability he might have known criminals in the chain.
If he was being interrogated more, the whole circle might have been cracked down, hence they decided to kill him. Having said that, it was just the most likely scenario and there was no proof I have more than this e-mail and sender. On the other hand, I am pretty much sure the nature of this information chain, which was actually led to the CIA and their asset.
This e-mail was linked to the CIA spies who gained a profit with illegal information, which was for sure.
If I was more involved in their insider circle, I could have grasped what this was all about, but I declined, many times, this kind of offer, hence I was excluded from their inner community. That was why I had no idea who made an illegal transaction in person.
Contrarily saying, I have been their targets for decades, not getting into their illegal circle, which was why the CIA and Japanese police intelligence hated me that much. If I am one of them originally, I have been secured to protect their interest, but I have been tortured to create a false confession as I am not. That was why they tried many times to kill me. There has been no fairness in this system and there is no rule of law under their governance.
