Which activity could indicate potential criminal or suspicious behavior?

Eliciting information and testing security can be a strong indicator of potential criminal or suspicious behavior because it shows intent to gather sensitive information or assess vulnerabilities. This behavior is often associated with individuals who may be planning illegal activities, such as theft, espionage, or other forms of assault on security systems.

In contrast, the other activities listed—joining community meetings, engaging in volunteer work, and participating in public events—are typically positive and constructive engagements within a community. They reflect social responsibility and an interest in community welfare rather than any intent to commit a crime.
