The nation's critical infrastructure provides essential services that underpin American society and sustain the American way of life. Critical infrastructure supports major aspects of our daily life such as electrical power, the potable water, transportation systems, first responders and hospitals in our communities, farms that grow and raise our food, and the Internet and communication systems we rely on to stay in touch.
Security and resilience of these critical infrastructure systems are vital components not only to public confidence, but also to the nation's safety, prosperity, and well-being. A public that can identify unusual and suspicious behavior is essential to protecting our communities from terrorist threats, whether the threat is homegrown or foreign.
"If You See Something, Say Something"® is not just a catchy slogan, but a strategy to follow to keep us all safe. Whether on your way to work, walking in your neighborhood, or out and about in your community, remember: We all play a role in keeping our communities safe.
Remember to stay vigilant and say something when you see signs of suspicious activity. Familiarize yourself with the signs of terrorism-related suspicious activity and when you notice something out of the ordinary, report who or what you saw, when you saw it, where it occurred and why it's suspicious to local authorities (or 911, in case of an emergency).
