There's no positive identification of Oswald in that clip.
https://www.c-span.org/video/?c4904439/user-clip-domingo-benavides-interviewYou're right, Otto.... In fact Benavides simply refers to Tippit's killer as " This other guy" Even though Benavides, at the time of the interview, knew full well that The WC had pronounced Lee Harvey Oswald as the lone nut killer.
Please note in the interview that Benavides clearly says that the killer turned and walked away and he was unloading his gun as he walked away.
Benavides says that the killer had TWO empty shells in his hand and Benavides saw him toss the spent shells into the bushes.
There is no way Benavides could have known that the killer had two spent shells in his hand ....unless B saw the killer eject the two shells.....
Thus, Benavides is describing the action of unloading a revolver that was NOT NOT a Smith & Wesson.... And therefore Lee Oswald could not have been the gunman...... Lee Oswald allegedly had a S&W revolver in his possession at the time of his arrest in the Texas Theater, and Benavides DESCRIBED the action of the killer and he was unloading a revolver that was NOT a S&W.
