Before I left, the SF Police Commision changed policy to require supervisory review and documentation (written on a template form) of every instance of 'Drawing and Exhibiting a Firearm'. This included BWC video review. So.....5 cops search a warehouse after a silent alarm goes off. Takes 30 minutes to search and clear this large building (not at all uncommon). That's 2.5 hrs of video to review.....for one incident.
