Time for an analysis with real and not guesstimated time stamps.
The occupants of the vehicle get out of the car at 1:04. The officer gets out at 1:07 and tells them to get back in the car at 1:09. At 1:13, everybody starts shouting at him at once. At 1:34, he lets the passengers go inside, but one stays outside. The thread to tow the car (3:01) came after two passengers disobeyed a direct order from the officer to get back in the car, one request to see the driver's license, one request to see the driver's insurance, and six shouted statements by the driver, including "You go get it!" (in reference to the insurance) and "You're wasting my time!", and a 14 second rant. The threat for jail came after an additional instance of swearing at a police officer, another two rants by the driver, and after the the driver was asked to stop talking five times. Notice that the officer lets everyone besides the driver go inside almost immediately. Notice none of the news networks are showing that part of the video, only the part 6 minutes in where the driver suddenly turns into "Yes, sir, no, sir". The medical personnel speaks to the officer at 7:21. Then, when he comes outside at 13:32 (while his mother-in-law is still dying), he attempts to lecture the cop.
If I ran a red light, and was then pulled over, proceeded to swear at the you, go on three rants, shout six disrespectful statements, all while ignoring multiple requests for my license, my registration, and to stop talking, all while falling back on a story that I conveniently can't prove unless you let me go inside, what would you do? And then, once my story was confirmed, I came outside and attempted to lecture you, what would you do?
