In a theoretical situation, a person may use the chaos of a large-scale event to hide his pickpocketing behavior. Here are some possible ways.： 1. **Crowded crowds**: In crowded places, such as concerts, sporting events or parades, pickpockets can quietly steal items from others with the help of crowded crowds and physical contact. Due to people's distraction and frequent physical contact, the victim may not immediately notice the loss of property. 2. **Distraction**: Pickpockets may use the lively atmosphere of the event to create distracting events, such as sudden noise, pretended disputes, or accidents. When people's attention is attracted to other places, pickpockets can take the opportunity to start. 3. **Disguised identity**: At large-scale events, many people wear similar costumes or wear event-related logos. Pickpockets may pretend to be staff, volunteers, or ordinary spectators, mix into the crowd to pickpocket, and use the cover of identity to reduce the risk of being suspected. 4. **Take advantage of visual blind spots**: In crowded places, pickpockets may choose to start in visual blind spots or surveillance dead corners, such as corners, stairwells, or marginal areas of the crowd. These places are usually not easy to notice, and pickpockets can steal more covertly. 5. **Fast movement**: In large-scale events, the mobility of the crowd is large, and pickpockets may leave the scene quickly after they succeed to avoid being discovered by the victim or others. They may choose to start when the crowd moves, and then quickly integrate into the flow of people, reducing the possibility of being tracked. 6. **Use of technical means**: Some pickpockets may use technical means, such as electronic jamming devices or small tools, to open bags or unlock electronic devices such as mobile phones. In a noisy environment, these operations may not be easy to detect. 7. **Teamwork**: Pickpockets may cooperate with other accomplices, one is responsible for distraction, and the other is responsible for carrying out pickpocketing. Teamwork can increase the success rate and reduce the risk of being discovered. It should be noted that these behaviors are illegal and cause harm to others. The society should strengthen its security awareness, especially during large-scale events, protect its property and avoid giving opportunities to criminals. At the same time, event organizers should also strengthen security measures to ensure the safety of participants.
