- 1: Missing persons hotline established for family or friends to report a missing or loved one connected to the incident.

Immediate Analysis
- Firing from afar is not often seen in mass shootings. You need to look to the 1966 University of Texas Austin tower shooting (killing 15 and injuring 31), or part of the 2016 Dallas shooting where the perpetrator was firing from an elevated position down below for similar cases. Most mass shootings occur in close distances.
- The role of social media in immediate notification and coverage of the event is apparent. Individuals at the music festival and across the city were snapping, twittering, and FacebookLive the attack as it unfolded. Rumors flared of other possible attacks, rumors which were quelled by the Sheriff.
- It is difficult to overcome the “Normalcy” bias. Many individuals at the music festival spoke about how they thought there were fireworks going off. Overcoming this bias can mean seconds more to act.
- Responding to an active threat event in a large public event area is extremely challenging. In addition to the shooting, the chaos of the attack can cause stampedes as people take actions. The sheer number of individuals at a large public event area can make response difficult, including the use of rapid deployment tactics to neutralize the perpetrator, as well as post-incident activities like reunification and witness management. Potentially thousands of people will need immediate reunification assistance, which can be challenged even further when considering issues that individuals who are minors, or individuals with access and functional needs require attention to.
