This ties in with the story from Minneapolis, because it turns out the officer in this story got busted because those body cams store the previous thirty seconds, without sound, prior to being turned on. This guy got busted because his body cam stored more images than he knew.
“...those body cams store the previous thirty seconds, without sound, prior to being turned on.”
So, they’re actually on all the time, but only keep 30 secs in the buffer until the record button is pushed?
