It doesn't help when one of the other guys from the same unit teaches totally contrary to getting off the car. One of the other issues we see in many videos is against multiple criminals, they inevitably will try to pull a flanking maneuver on the lone officer. It is why I try to get folks off the car enough to see an opponent coming from aroun the ends of the vehicle, and to be able to engage them uninhibited. According to the other one, this leaves you open to threats from upper stories or high ground......which I have never seen in the CONUS criminal side, but is an obvious issue with the Mogidishu world.
My best friend and long time mentor always said he treats room combat like a miniature battlefield as far as trying to maneuver against opponents to exploit their weakness. Obviously Mike Pannone is using the same principles with vehicles and it makes perfect sense. I taught several things different than most standardized LE protocols to maximize effectiveness with less risk for officers. With that said, it is also critical that very standardized felony stop procedures are used to ensure everyone is on the same page and amped up cops are not "winging" it. These things are very much a balance.
