The St. Louis Cardinals have received federal certification giving the organization legal protections in the event of a terrorist attack at Busch Stadium.

DHS certified the Cardinals under the Support Anti-Terrorism by Fostering Effective Technologies Act, known as the Safety Act.

The act encourages sports teams, entertainment venues and other organizations to develop anti-terrorism technologies and practices. In return, it places limits on lawsuits that could be filed if a terrorist attack occurs.

U.S. Senator Claire McCaskill, the top-ranking Democrat on the Homeland Security and Governmental Affairs Committee, praised the decision.

“I’m thrilled the Department of Homeland Security awarded the Cards a designation under the Safety Act—it’s clear they’re placing the highest priority on protecting their fans, players, and employees.” McCaskill said. “Terror attacks are increasingly occurring around the world on soft targets like stadiums and concert venues, and the Cards are confronting that threat head-on.”

According to an LA Times report, Cardinals security director Phil Melcher said in an interview that upgrades include background checks on all employees and vendors and the installation of barricades to prevent vehicles from ramming the stadium. He said the Safety Act application also requires tracking of metrics to prove the measures work.
