How to identify suspicious activities or persons

Activities or behaviour that do not seem normal can be suspicious. This applies not only to public areas, but also to our own communities. Some signs to be aware of are:

General behaviour

Repeated entrances and exits from a building, or wandering around a public area
Nervousness, nervous glancing or other signs of mental discomfort
Keeping hands in pockets or constantly adjusting clothing
Unusual behaviour, such as patting
Items or projected angles under clothing

Radicalisation

Extremist religious propaganda or beliefs
Expressing the belief that violence is justified
Idolising, showing support or sympathising with terrorists and their causes
Influencing others to support terrorism and/or participate in terrorist activity
Displaying insignia or symbols in support of terrorist groups
