DES MOINES, Iowa -- A little more than 24 hours had passed between a bombing after an Ariana Grande concert in Manchester, England, and the Red Hot Chili Peppers taking the stage in Des Moines.
Concertgoers at Tuesday's Chili Peppers show say the bombing was on their mind, but not at the forefront.
"Either people are going to be deterred or not. If they are deterred, they got their message across, but by going here, in my opinion, that's kind of saying I'm not going to be terrified of terrorism," said Todd Etheridge.
Security experts say in America, some of the biggest events like the Super Bowl have seen changes in arena security, with attendees having to move through layers of checkpoints starting farther away from the arena. They say copying that model for large concerts or events could help lessen the damage if one of these attacks was to be carried out.
Tom Conley is the president of the Conley Group, a private security firm, and says being aware of your surroundings is key, whether you're in Des Moines, another big city, or abroad.
"If someone is going to a concert with a friend, they're coming in, talking back and fourth and looking at going in the venue. Someone that's going to kill people is looking around, they're looking at the crowd, they probably have some nervous behavior," said Conley.
Wells Fargo Arena has not indicated it will change any security practices based on the attacks overseas.
