"Security is both a feeling and a reality. The propensity for security theater comes from the interplay between the public and its leaders. When people are scared, they need something done that will make them feel safe, even if it doesn't truly make them safer. Politicians naturally want to do something in response to crisis, even if that something doesn't make any sense."in reference to:
"Unfortunately for politicians, the security measures that work are largely invisible."
