It’s the last place you’d expect to see kids smiling, and yet the youngsters were all grinning as they walked into KinderMourn on Feb. 18.

The non-profit organization in Charlotte, NC, works with families who have lost a child, and on that day veteran police officer Chad Webster and his pigs Sgt. Snuggles (Sarge for short) and Frank were waiting for the kids as they arrived.

“They never smile and there they were, just laughing at the pigs,” Webster told People.

And that’s the point. The 44-year-old father of four started what he calls the Bacon Response Team about eight months ago. He and the pigs have visited schools, the cancer ward at the hospital and community events, trying to spread joy and help kids and adults get comfortable with police. A former patrol officer and domestic violence detective, he now works as a community officer for the Charlotte-Mecklenburg Police Department.
