The Problem:
Stadiums and concerts are popular, creating large and ruckus environments where fans can turn into fanatics within the drop of a hat (or mike for that matter) and when large crowds gather, and alcohol is involved, security agencies become challenged to keep up, thus, creating a bonanza of various types of fraud, attacks and general disruptiveness.
After a sold-out mega-star event, they came to the conclusion, that they didn’t have enough security to handle and monitor the increased foot traffic. They had been confronted with violent perpetrators that become opportunist, wreaking havoc on innocent attendees.
