The best way is to remember the appearance of the suspect in the first place. Now everyone has a mobile phone to take photos quietly, and then immediately call the police, simply explain where the person is now and in what direction, and then add an alarm WeChat or something to send the photos directly. If it is not convenient to take pictures, just tell the police officer about the clothes, color, height and appearance of the suspect.

To tell the truth, don't take the initiative to call this person, or as TV said, there is a chat without a word, because at this time, if the suspect is really a kidnapper, then he is likely to doubt everything. And once he suspects, he may pull out a knife and give you two knives at any time.

Some people also say that shouting is to attract everyone's attention, and it can also attract the suspect's attention and let him stay and see something. Is he going to engage in illegal and criminal activities again, and will he stop to watch the fun? Some people even said that people around him shouted that he was abducting children. I don't deny that there are many good people, but the other side is a gangster. If the other person becomes nervous because of your roar, it will change from abducting children to turning them into hostages. And there are many good people, but what if many people didn't have good people at that time?

We should not oversimplify or complicate things, but should consider the consequences of doing something. There was a child kidnapping case here before. A teacher was suspicious, took photos and immediately called the police. After more than ten minutes, the other party was arrested by plainclothes police, and there were no casualties. If the teacher says loudly that he is abducting children, or goes directly to the classroom, can the abducted children be rescued and the criminals arrested in ten minutes?

Let's not exaggerate reality just because we watch TV. The bad guys on TV often die because they talk too much, but the bad guys in reality can solve it by giving you a shot or a knife. What we can do when this happens is to take pictures at the first time, or remember people's looks and related information and call the police. Public security organs have police stations everywhere, and they will contact the nearest police station or call the police immediately. We should not provoke gangsters because of our kind behavior, which will complicate simple things.

Finally, the bad guys are not fools, and neither are we. Rabbits bite when they are in a hurry, let alone gangsters.
