Chen Hong, a lawyer of Heilongjiang Hongqi Law Firm, expressed his views on this case: Gong Runbo tricked and molested children and killed many people, which was shocking. Although the occurrence of such cases is individual and accidental, it is a great threat to people's sense of security, and it makes people feel creepy as soon as they hear about it. Of course, we don't have to feel "dangerous" and there are killers everywhere, because after all, the bad guys in our society are extremely individual. In addition, if you have a certain sense of self-protection, you can sometimes get out of danger. From the point of view of minors, although primary and secondary school students are still young, they have contacted the society to varying degrees. At present, there are still some problems to be solved urgently in social security. There are still illegal and criminal phenomena in society, and students are sometimes infringed by criminals. Therefore, it is necessary for everyone to learn to correctly understand the people and things they encounter, distinguish between right and wrong, distinguish between truth, goodness and beauty and falsehood, ugliness and ugliness, improve their vigilance against all kinds of infringement, and eliminate paralyzed thoughts and lucky psychology. At the same time, we should also establish self-prevention consciousness, master certain safety prevention methods and enhance our own prevention ability, so as to deal with abnormal situations calmly, tactfully and bravely.
