Like what? This isn’t a battlefield, the FCC isn’t going to let them do any jamming and they sure as hell aren’t putting up CIWS cannons all over the place.
I've seen multiple NFL games be stopped in the middle because of one person flying a drone. They take this stuff extremely seriously - I wouldn't be surprised if the entire concert was put on hold until the drone was stopped. The people who have done this have served jail time and been hit with 6 figure fines.
