I wonder if any LE ever saw it, the SD. Fosler could have taken the SD memory out before he picked up the minor, then a naive LEO could have just recoveted the dashcam, not even knowing about the internal SD. That would be extremely stupid of F to keep it running during sucj a crime. But I don't understand the atty saying they could still hear the audio. That should be on the sd card too.
I just reread it, defense atty does say they can still use the audio. That's beyond my knowledge of dash cams, having a separate copy of just the sound. Which would akso be exceedingly stupid to keep running while he kidnaps a minor.
