(CNN) -- Nearly two years after the deadliest mass shooting in modern US history left 58 people dead in Las Vegas, the city's police department has released a report detailing the lessons learned.
The gunman fired on the crowd of about 22,000 people from the 32nd floor of the Mandalay Bay Resort and Casino in October 2017, leaving hundreds injured.
In a report released Wednesday, the Las Vegas Metropolitan Police Department cites 93 recommendations in the aftermath of the shooting, some of which have been implemented.
Here are the key highlights:
- Chaos after false calls of active shooters: When reports of gunfire emerged, officers rushed to the scene. Others rushed away from the actual scene -- to clubs and other locations where panicked callers reported active shooters and suspicious people. Other officers self-deployed to scenes all over when they heard calls of active shooters.In the immediate aftermath of the shooting, the response was chaotic and the police department could not account for its personnel.
- Lesson learned: A more controlled response of resources is needed to avoid overwhelming officers and dispatchers with 911 calls of false shooters, the report says. The police department recommended several measures, including managing self-deployment during such cases and developing a software to account for resources.
- Helping families in the aftermath of a shooting: During a mass shooting, the report says, connecting families and providing information on resources are the responsibility of the coroner, the report says. A family assistance center provides assistance and information to families of those killed, injured or otherwise affected by the mass shooting. In this case, FBI agents from the Orlando field office who were involved in the response to the Pulse Nightclub shooting flew to Las Vegas to help. The family center was crucial to facilitating support and exchange critical information, the report says.
- Timeline and conspiracy theories: The rush to provide information on the timeline of events later became problematic and sparked conspiracy theories, the report said. When the shooting first happened, police were under pressure to follow protocol and provide a timeline of how it unfolded. But the sheer amount of data and various devices that had different times later made people question the police version, sparking conspiracy theories on the shooting that live on to this day.
There may never be an exact timeline due to the sheer number of internal and external data that different people used, the report said.
As a result, the department will focus less on times and describe it as a sequence of events as opposed to a timeline.
