Bagua Handgunning

I thought this was pretty interesting, using Bagua footwork in police work. The instructor is using good body mechanics and leverage, I just wonder if these doughnut-eaters can grasp the concepts. It certainly seems that the stable yet intricate footwork would be useful when turning corners in a building.
Years ago I asked my Aikido instructor, who is a County Sheriff, how skilled most police officers are in unarmed combat. Not suprisingly, he said they learned a few simple things at the police academy but little else. Now, maybe in the big city that's different. But he frankly told me that it takes so much time to be skilled in unarmed combat that most police officers, like the general public, just never put the time in. Instead, they rely on the radio, the nightstick and the handgun.
I'm curious if any officers out there care to comment on the training demonstrated in this video...
