From: "Jane's Workplace Security Handbook" published by AIG
"It is difficult to overstate the importance of implementing proactive facility security measures to combat threats to the workplace. Terrorists, extremist groups, disgruntled loners or criminals will usually target locations that offer the path of least resistance. This path of least resistance may not be immediately obvious to those who work in a facility. Despite this, prior to the terrorist attacks of September 11, 2001, conducting a comprehensive threat assessment in places of business was the exception, not the rule."
