Which of the following is NOT a step in self-protection measures against terrorism?

The correct answer highlights that actively engaging unknown individuals is not a part of self-protection measures against terrorism. Engaging with unknown individuals can increase risk by drawing unwanted attention to oneself and potentially leading to dangerous situations. Instead, self-protection emphasizes awareness and caution, promoting behaviors that minimize risks and enhance personal safety.

In contrast, avoiding revealing plans, carrying identification, and staying mentally prepared are all proactive and prudent measures for self-protection. Avoiding the discussion of personal plans helps maintain privacy and security. Carrying identification is important for identification purposes in emergencies, and staying mentally prepared can foster a better response in crisis situations, contributing to overall personal safety. The essence of self-protection against terrorism is to promote vigilance and caution, making active engagement with unknown individuals counterproductive to these goals.
