In Mineola, New York, A security guard stopped an armed robbery, and was able to subdue the suspect without any loss of life. Authorities called the situation "a life-and-death struggle." The security guard on duty became alerted to the situation, and immediately confronted the suspect. As Americans are still in a state of high alert in wake of the San Bernardino attacks, a security professional's attention to detail and state of readiness should never be relaxed.
