We all noticed something changing with Columbine in 1999. Through 9/11, Virginia Tech, Ft. Hood, Sandy Hook and the Aurora theater shooting, terms like “active shooter” and “lockdown” have made their way into our daily – yes, daily – lexicon. As risks and threats change, so too must your approach to protecting those who operate and frequent your property – be it a shopping center, a school campus, a hospital or a sports stadium. The phrase “can’t happen here” is obsolete.
