A security guard's job is often about preventing problems before they become emergencies. But sometimes, situations escalate despite those efforts, putting the guard, employees, customers, and surrounding community at risk.

A recent incident at a Whataburger on San Antonio's South Side demonstrates why businesses operating late at night—and especially businesses that experience high customer traffic—may benefit from a professional security presence.

On a seemingly ordinary Sunday morning at CrossPointe Community Church, more than 150 people gathered for worship. What happened next would shake not only that congregation but serve as a tragic reminder of how perilously close many places of sanctuary are to becoming battlegrounds — and how decisive, often unseen, acts of bravery can avert catastrophe.
