Those were Shannon Johnson’s last words on December 2, 2015, as he shielded a coworker from a barrage of bullets raining down on the San Bernardino, CA, health department Christmas and holiday party. Johnson was sitting next to Donna Peraza at a holiday luncheon for San Bernardino County environmental health employees on December 2, 2015, when a pair of attackers—one of whom was known, and a coworker actually—with assault rifles began spraying bullets. Peraza says she and Johnson sought cover beneath a table when he tried to shield her. Johnson was among 14 people killed in the attack. Peraza was shot in the back but survived. Shannon’s selfless act of ensuring the safety and well-being of a colleague resulted in his death—but there is a lesson to be learned here in his passing: We are relentlessly compassionate, and we all learn from our experiences and life journey. While such events will long be forgotten, the scars and the emotional toll will persist. It is with appreciation to Mr. Johnson and his heroic acts and to remember those in public health who have sacrificed so much for the communities they serve that we wish to share public health lessons learned.
