Festival-goers should expect enhanced security at Lollapalooza this weekend in Chicago, as more police, fencing, bag restrictions and airport-style screening are added to the annual Grant Park event.

The security industry’s calendar seems to revolve around a few key events: ISC West, ASIS International’s Global Security Exchange (GSX), ISC East… But have you ever considered how much effort goes into securing tradeshows and other large-scale events?

“The country’s come quite a long way. Fans now expect security, and it made me feel good that I could take my wife and daughter to a baseball game, spend a couple hundred dollars, and feel safe about it,” says Adam Stockwell, Vice President of Security for the Milwaukee Bucks.

The Trump administration urged Congress this week to give it new powers to disable or destroy threatening drones. According to Reuters, written testimony from David Glawe, undersecretary for intelligence and analysis at DHS, and Hayley Chang, DHS deputy general counsel, said that “terrorist groups overseas use drones to conduct attacks on the battlefield and continue to plot to use them in terrorist attacks elsewhere. This is a very serious, looming threat that we are currently underprepared to confront.”

Chicago lawmakers are attempting to amend the Freedom from Drone Surveillance Act to permit law enforcement to fly surveillance drones over “large scale events” in Chicago. The bill references festivals and concerts, but ACLU Illinois says the amendment could empower police to fly drones over political protests and rallies.

As tragedies like Vegas, Orlando and Sandy Hook stay top of mind for Americans, venues of every size across the country should assess how they tackle the difficult questions raised when evaluating security concerns for their events.
