Pretty messed up and paints a horrible picture of the motorcyclist, particularly us high powered sport bikes.
Now since the initial take off is off camera view it's impossible for me draw a conclusion. Why you ask ???
We all know how the bike jacking at a light works by thugs and low life's there is no way to tell if he thought he was getting jacked or when the cop put his hand on his shoulder he turned saw him and then ran.
The Trooper that stopped me knows how to sneak up on a motorcyclist that they wanted to stop, but didn't turn on their lights or sirens to spook him to run.
You approach from the blind angle keeping out of the rear view, you will get close enough to see both his hands( just to be sure he is not armed).
Then quickly reach for the key with one hand while you have your other hand on your firearm and turn the bike off. The bike is off you are now next to him to react to what way the rider decides to act. Rider passive ??? remove key cop keeps key and tells you to push the bike out of traffic. Rider gets stupid and aggressive, cop kicks the bike over and draws.. I speak from personal experience freaked me out but I didn't get a ticket cause I wasn't the one they were looking for
I don't know how it should be done but I am confident the way officer did it is not the right way
