Set a perimeter and wait was pre-columbine law enforcement tactics for active shooters. Current training is that first responding officer goes in hunting for shooter, with backup or no backup. It is emphasized to bypass everything and go to sounds of gunfire and eliminate the threat asap. I would certainly hope this video is lacking context, and there are already officers inside handling business.
