Cenxi police issued a notice offering a reward to the suspect. Why is this suspect's anti-reconnaissance ability so strong?

A major criminal case occurred in Mulang Village, Cencheng Town, Cenxi City. After investigation, Gao Meixin is suspected of committing a major crime and is now fleeing.

Strong anti-reconnaissance ability is indeed an objective ability, and the police will detect cases from the routine handling procedures. Since it is a routine procedure, it is because it conforms to the criminal psychology and behavior of most criminals. It is reasonable to handle the case according to the routine procedure. Occasionally, you will encounter some magic levels, which will increase the difficulty of detection or need to change the way of solving crimes. It's not that the police are unskilled, but that the criminals are really cunning. After all, the strong have the strong. Anti-reconnaissance refers to the use of confusing and destructive means to prevent the enemy from tracking and detecting itself to ensure its own safety.

The villain in the movie doesn't make threatening phone calls for more than a certain period of time, but also changes his position from time to time to prevent the police from finding the exact address of the phone. Anti-reconnaissance behavior is very complicated, including making fake scenes or transferring crime scenes, making fake physical evidence at the scene, excluding all evidence that may expose oneself, using people's habitual thinking to conduct abnormal behavior, disguising, and using acquaintances among investigators to understand what happened. If you can ensure your own safety and negotiate with the police, it shows that the other side has strong anti-reconnaissance ability. A person's anti-reconnaissance experience depends on his own criminal experience or all investigation experience, and on his own knowledge and technical ability. ?
