Former Defendant "Proof that I was alive without thinking deeply"

In January, a 29-year-old former defendant, who was arrested and charged with holding the manager as a hostage at a Yoyogi barbecue restaurant in Shibuya-ku, Tokyo, and was convicted of a suspended sentence, responded to the interview for the first time.

He explained that he used a fake cardboard bomb to threaten him, and he decided to start the incident about an hour before he entered the store.



He recalls his feelings at the time, saying, "I wanted to end his life, and when I was standing up, I told the police officer who came to persuade me to kill him for the time being."

Last August, a man in his 40s, one of the victims of a passenger being cut off on the Odakyu Line in Tokyo, responded to the interview.



The man said, "Every morning, the moment I grab a knife to make rice, the sight of the blades scattered on the floor spills over my head. I tell myself not to think about the incident." ..



On top of that, he said, "I don't want to know the motives of the criminal. I don't want to know the motives of the criminal. I am. "

Expert "Dissatisfied with the spread of SNS compared to others"

Professor Takayuki Harada of the University of Tsukuba, who specializes in criminal psychology, said, "The common point is that I am very desperate for my life and want to end my life. I'm dissatisfied with other people, and I think it's because of my surroundings that I'm going to be hostile to society. It is necessary to properly analyze and think about what kind of measures are necessary. "
