Shortly after dawn on Monday, a frantic livestream from Billy Joe Cagle—a 49-year-old convicted felon from Cartersville, Georgia—ignited a chain reaction that ended in the thwarting of a possible mass shooting at Hartsfield‑Jackson Atlanta International Airport. In his broadcast, Cagle declared his intention to “shoot up” the world’s busiest airport and appeared en route to carry out the threat. His own family, alarmed by the footage, called local law enforcement—and their quick action helped stop what could have been a catastrophe.
According to Atlanta Police Department Chief Darin Schierbaum, the family contacted the Cartersville Police Department after spotting the livestream and realizing Billy Joe Cagle was about to head to the airport. At approximately 9:30 a.m., Cagle arrived in a Chevrolet pickup, parked curbside at the South Terminal and briefly entered the airport unarmed. Surveillance and body-camera footage show him lingering near the TSA checkpoint moments later.
Less than fifteen minutes after the tip, Atlanta police arrived on the scene. At about 9:42 a.m., officers located Cagle inside the terminal and took him into custody without incident. Meanwhile, a search of his pickup truck uncovered a loaded AR-15 rifle and 27 rounds of ammunition hidden inside. He did not yet have the weapon in his possession when arrested, but investigators say his intent was clear: scope the terminal first, then return to his vehicle for the rifle and carry out his plan.
Mayor Andre Dickens and police officials praised the swift coordination among law enforcement and Cagle’s own family for preventing what could have been a disastrous loss of life. “This could have been tragic but was averted,” Mayor Dickens said, noting that “27 or more lives could have been lost.” Law enforcement is now working with federal partners to determine how Cagle obtained the rifle, since as a felon he was barred from firearms ownership.
Cagle has been charged with multiple offenses, including terroristic threats, criminal attempt to commit aggravated assault, possession of a firearm during the commission of a felony, and possession of a firearm by a convicted felon. Officials also indicated that they believe Cagle might have been experiencing a mental-health crisis at the time of the incident.
What stands out in this story is not just the threat, but the quick instinct of a family to reach out—and the immediate reaction of local police that followed. In less than half an hour from the first tip, a potential tragedy on one of aviation’s busiest terminals was stopped in its tracks.
For now, Cagle remains in custody, and the investigation continues as authorities dig into how a felon acquired such a weapon and whether any further actions or charges are warranted. In a modern world where mass-casualty threats loom large, this incident is a stark reminder: sometimes the best security begins before law enforcement ever
shows up.
