The recent mass shooting at a ‘Madden 19’ esports competition at a Jacksonville, Florida bar left three people dead and eleven more wounded.

The most glaring issue in the wake of the shooting is the general lack of security for the event. Organizers apparently assumed strict security measures were not required for the small event.

Now, the entire esports industry is reviewing its methods and how to better protect competitors and huge numbers of fans. Ticket sales for esports in 2017 came in at an estimated $184 million, according to PricewaterhouseCoopers. These public events have become increasingly popular among gamers and non-gamers, drawing large crowds to watch competitive playing of well-known games, with ‘Fortnite’ being among the most popular.

The attention that these events draw also represents an increased potential threat level. Upcoming esports events with major corporate sponsors including the ESL One New York esports competition set for September have been forced to reassess their security plans.
