Perhaps there is something of evidentiary value in that footage if, for example, the officer inquired about the vehicle's connection to the Moscow homicides and BK responded. Who knows? Maybe the officer asked follow-up questions about apparent scratches/bruises on BK's hands. It's a long shot, but having just been to my local precinct to make a report and receiving the 3rd degree about why I didn't report earlier, it seems possible to me that the first officer was more "inquisitive" than the second.
