The Circle on County Road 12

At 4:18 on a humid Thursday afternoon in Polk County, Florida, traffic slowed along County Road 12 beneath a sky heavy with late-summer clouds. A patrol SUV sat angled across the shoulder, red and blue lights flashing against the dull shimmer of asphalt. Drivers eased off their gas pedals out of instinct. A few lifted their phones. From a distance, the scene looked tense: a uniformed officer on his knees in the road and motorcycles arriving in a low, steady rumble.
