Useless, horrible video tells us nothing except he wouldn’t stay down and went into his car in a suicide-by-cop death move.
Halfway through the second video you clearly see him reach back with the tazer and see the pursuing officer run into the nearby car.
Maybe I watch the two videos far more closely, but it is clear he refused arrest, took one of the tazers, used said tazer towards an officer and was being arrested for under the influence.
