What does it indicate if a suspect possesses a police radio scanner?

Possessing a police radio scanner can indeed suggest an intent to evade law enforcement. This behavior may indicate that the individual is monitoring police communications to gain information about police activities, such as patrol locations, ongoing investigations, or emergency responses. By having access to this information, the suspect could potentially plan their actions in a way that avoids detection or capture by authorities, which aligns with criminal behavior or an intent to navigate law enforcement efforts more effectively.

Having a scanner could be viewed as a tactical advantage for someone engaged in illegal activities, allowing them to remain one step ahead of the police. While other interpretations are possible, such as a general interest in law enforcement or a claim to have an affiliation with law enforcement, those interpretations do not align with the purpose of using such a device in a criminal context. Therefore, the most logical inference is that it indicates an intent to evade law enforcement.
