In a brightly lit room, a karate class is underway. One instructor, dressed in white martial arts garb, demonstrates a kick for a second instructor wearing casual black attire. About a dozen students sit around the perimeter, watching. The room, with tiled floors and several windows, is decorated with red, white, and blue fabric. The room has ceiling fans and fluorescent lighting. A smartphone watermark identifies the video was taken with an itel A60s 4G.
