Armored car companies do more than provide secure shipment of money. They also store cash for banks and businesses, and hold millions on any given day. Security in these facilities is intense, and for many would-be robbers, bypassing such defenses is an impossibility. On September 13, 1997, Allen Pace found a way to beat the system. As the regional safety inspector at the Dunbar Armored facility in Los Angeles, Pace was able to determine the weaknesses in each security measure. For months he planned and calculated and when the time was right, he recruited a gang of childhood friends to pull off the score. With military precision, Pace and his crew evaded the security cameras, ambushed and neutralized the facility's guards, and made off with nearly $19 million in 30 minutes - the largest cash heist in American history.
