From the perspective of criminal psychology, thieves usually consider the following factors to minimize their own risks when choosing the target of the crime:： 1. **Property value and ease of sale** -**Property value**: Thieves tend to choose targets with higher property value. Because higher-value property can bring greater economic returns, after committing the theft, more benefits can be obtained by selling these property, which is very attractive to the thief. -**Easy to sell**: Property that is easy to get rid of and realize is also the focus of thieves' attention. For example, electronic products, jewelry, brand-name clothing, etc., These items have relatively stable demand and circulation channels in the second-hand market or the black market, and thieves can more easily convert them into cash. 2. **Reachability of goals** -**Physical accessibility**: The thief will choose those places that are easy to enter as the target of the crime. For example, houses where an effective access control system is not installed, window protection measures are weak, or door locks are easy to break. They will observe the surrounding environment of the target location in advance, looking for easy escape routes and hidden entrances to ensure that they can enter and leave smoothly during the crime process, and reduce the risk of being caught on the spot. -**Time reachability**: Appropriate crime time is essential to reduce risk. Thieves usually choose to commit crimes during a period of time when there are fewer people in the target location, the monitoring system is not operating frequently, or the security measures are relatively lax. For example, most residents rest at home at night, there are few pedestrians on the streets, and staff evacuate after business hours in commercial places. These hours provide more favorable conditions for thieves to commit crimes. 3. **Targeted preventive awareness and security measures** -**Awareness of prevention**: If the thief perceives that the target has a high sense of prevention, such as high vigilance, sensitivity to changes in the surrounding environment, or frequent preventive measures, they will tend to choose other targets. On the contrary, for those who show negligence and do not pay enough attention to the safety of their own property, the thief will think that the possibility of successful theft is greater and the risk is relatively low. -**Security measures**: Perfect security facilities will act as a deterrent to thieves. For example, in places where surveillance cameras, alarm systems, and frequent security patrols are installed, thieves will regard them as high-risk targets and avoid them. On the contrary, places with weak security measures, such as old residential areas and small shops, are more likely to be the target of their crimes. 4. **Surrounding environment and concealment** -**Surrounding environment**: Thieves will consider whether the environment around the crime site is conducive to them to hide and escape. For example, there are more obstructions, alleys and alleys criss-crossing the surrounding area, or areas with complex human movement, which makes it easy for them to quickly hide their whereabouts after committing the crime, mix into the crowd and escape the scene, increasing the chance of avoiding pursuit. -**Concealment**: The concealment of the target itself is also an important factor. Thieves usually choose places where their belongings are stored more hidden and are not easily discovered by others. For example, unlocked drawers, hidden storage rooms, or corners that are not covered by monitoring, etc., can reduce the risk of being discovered on the spot. 5. **Criminal record and familiarity** -**Criminal record**: People with a criminal record of theft will be affected by past experience when choosing the target of the crime. They will avoid choosing areas and target types that have caused them trouble or are more risky. On the contrary, they tend to choose targets that they think are relatively safe, easy to get, and not easily associated with past criminal acts. -**Degree of familiarity**: Thieves often prefer a familiar environment. They are familiar with the local terrain, the rules of personnel activities, and the security situation, so they can better plan the route and timing of the crime, and avoid possible risk points in advance. In addition, the familiar environment also makes them feel more secure in the process of committing crimes, reducing the uncertainty and tension caused by the unfamiliar environment, thereby reducing the probability of being discovered.
