The dialogue isn't realistic, in my opinion, since not one police officer mentions the reason for stopping the driver. Also, there isn't any reply from any officer, apparently acquiescing to the tirade from the driver?
Unfortunately the dialogue is all too real.
The officer is not obligated by any law or regulation to
immediately tell the motorist the reason for the Stop and usually does not interact with the motorist on that level until he has first identified the motorist and establishes that the motorist is legally operating the vehicle. The officer as a trained Observer is also evaluating the overall situation based on the response and demeanor of the driver... One of the things he is immediately assessing is whether or not the driver may or may not be a threat to his safety or well-being as this is Paramount in the beginning of the traffic stop as it is always an unknown.
Nowadays acquiescing in any fashion when dealing with a motorist in the above scenario regardless what the officer says especially if the motorist is recording the encounter will be taken out of context and negatively portrayed in the media by people who have an axe to grind and have no idea why the officer does what he does nor do they care... they will purposely give it a negative slant in an effort to broadly paint all police officers as jack-booted Thugs and Stormtroopers in order to further their cause or simply for higher ratings. With the hostile environment that persists today exasperated by liberally biased media and radical liberal organizations such as BLM it seems now that is better for the officer to remain silent because anything he says will be unfairly used against him.
This ladies and gentlemen is what the state of policing in the United States is coming to... And then we will all be asking ourselves why has the crime rate exploded and why aren't the police as effective as they could be... So endeth the lesson.
