2. Surveillance
During the planning phase, a terrorist will often conduct surveillance on a possible target. Watch for the following suspicious behaviors:
• Taking photos or videotaping entrances and exits
• Trying to conceal their actions
• Asking inappropriate questions about schedules, the facility or security
• Using binoculars or drawing diagrams
