Sometimes it’s better to disarm than to arm. Put another way, humor can be both a powerful leadership and tactical tool for security. Humor is tricky business in the security world, however. Briefing staff on warning signs of workplace violence, precursors of terrorist attacks, contingency plans for natural disasters, and methods of corporate espionage doesn’t exactly lend themselves to one-liners. Dealing with most security incidents isn’t a laughing matter. Moreover, a security professional who cracks jokes, or even shows a lighter side on the job, risks being viewed as unprofessional.
