Negligent security cases arise when an incident occurs on someone else’s premises and the harm is tied to security measures that were not reasonable for the risk.
In Pierre, common fact patterns we see involve:
- Assaults near entrances where doors, locks, or access control weren’t functioning as intended
- Incidents in parking areas where lighting, sightlines, or supervision were inadequate during peak arrival/departure times
- Workplace or business hallway assaults where staff were aware of prior problems but response and monitoring were inconsistent
- Event-related incidents around venues where pedestrian flow increases and security protocols should be tightened
The goal isn’t to claim a property owner guarantees safety. Instead, the law looks at whether the owner or business acted reasonably given what they knew or should have known.
