On Sept. 11, our thoughts turned to the day 17 years ago when terrorists crashed airliners into the World Trade Center, the Pentagon and a field in Pennsylvania. The attacks killed more than 3,000 people and injured more than 10,000. It was the deadliest terrorist act in U.S. history and the most devastating foreign attack on American soil since the attack on Pearl Harbor.

In the aftermath, many U.S. citizens held the view that the attacks had “changed the world forever.” The Bush administration announced a war on terrorism, with the goal of bringing Osama bin Laden and al-Qaida to justice and preventing the emergence of other terrorist networks.  This marked a turning point in our country as citizens thought terrorism was something that happened in other countries.  Federal, state, local agencies, private citizens, and the private sector began sharing and collaborating to bring more safety and security to America.

Stadiums and arenas around the country held many concerts after 9/11 and spectator sports returned as well, bringing comfort to the country.  As places of mass gatherings, they were soft targets for the adversary.  However, with the response to harden the infrastructure, develop smart practices, integrate technology and provide training that makes it more difficult to attack our venues, we will continue to stay on the prevention side of the equation.
