The audio was from the cop, who was transmitting it back to the police vehicle from the foot pursuit. I assume it’s why when he started to get out of transmit range the audio started breaking.
There was no two minute long fight between these two as you suggested. If a timeline which confirms a two minute long fight exists, I would like to see the link to that.
Thanks.
All of the timelines are determined by video clips that are shown and narrated on Conservative Treehouse, incliuding the section where they conclude that the struggle lasted almost two minutes.
