In order to prepare the future, we must learn from the past. In this issue, we will look back on major incidents impacting the sports and entertainment industry and identify gaps and solutions surrounding these events such as technology, training, policies/procedures, and private-public partnerships. Several of the incidents we will cover include: Columbine Shooting (1999), Boston Marathon Bombing (April 2013), and the Las Vegas Shooting (October 2017), among others. The topics we cover in this issue relate to the 10th anniversary of our National Sports Safety and Security Conference and Exhibition on July 9-11, 2019 in New Orleans as we “Learn from the Past to Prepare for the Future.”
