• Unusual thefts of chemicals or explosive substances.
• Unusual thefts of weapons or vehicles, including planes or boats.
• Business patrons or individuals who make unusual inquiries about public utilities, large public gatherings, transportation centers, or governmental buildings.
• Anyone making requests for information, particularly about security or procedures for high-risk buildings or events listed above.
• Anyone attempting to appear ‘normal’ in their behavior, such as portraying themselves as a student or tourist.
• Any person carrying identity documents that are issued using various names.
