At a children’s event called Reading Roundup in Lodi, Calif., on Aug. 24, a police SWAT officer was showing off the department’s truck, vest and other gear when a boy, around 6 to 8 years old, managed to pull the trigger on his Glock 35, shooting the officer in the leg. Police say because the gun was in a holster to accommodate the attached flashlight, the trigger was more accessible.

“It doesn’t have an external safety or anything like that,” Lt. Sierra Brucia told the local CBS affiliate. “The gun functioned how it was supposed to. When the trigger was pulled, the gun went off.”

Police are keen to question the child to see what went wrong. They are also investigating their own protocols to prevent this from happening again. Here is today’s report.
