It doesn't make sense to you because it doesn't comport with what you want to believe is true. I do not know if a supervisor was even on scene when Oswald was arrested. And there is no way in hell I will believe any cop, regardless of rank, is going to facilitate the escape of a murderer of a brother officer. That is stuff of fallacy and fantasy. It just wouldn't have nor will it ever happen. Period. End of story.
Moreover, your thesis doesn't make sense because if a Dallas supervisor facilitated the escape of a murderer of one of his brother officers, it would mean that that supervisor was in on the conspiracy. That I do not believe.
When you speak of policemen, you come across as naive to the point of being childlike. Have you seen the movie, based on the real story, Serpico? Police corruption is, and always has been, extremely common. In Serpico, his corrupt partners arranged for him to be killed by a drug dealer.
TRH,
You can allege I am naive, but to believe what you want me to believe would mean that Dallas PD was in on the conspiracy. That I do not believe.
Here is what I do know is factual: there is an inverse correlation between number of conspirators and ability conceal a conspiracy. The more people who know what happened the less secure the secret.
You gotta get beyond Serpico. It was a film with elaborate use of artistic license. To extrapolate from a single movie pandemic corruption is, well, naive.
