I am not arguing trivial details. The way it is presented in reports is that it was a crime scene. Use your imagination
Why was scheduled driving on the median with a cop on foot chasing him
To get out of traffic and out of danger of oncoming traffic to protect himself and the officer. Why did he stop 60 feet ahead and get out of the car and why did the cop immediately put him in cuffs and arrest him without asking for identification for an apparent traffic violation which is a misdemeanor?
Fourth Amendment violation right there....
