Marvin Wise the only dirty cop alive today that was at Dealey Plaza on November 22, 1963.
Mr. Wise was interviewed by the HSCA in 1977 and the FBI in 1992 because photographic evidence shows that he had:
1. Dirty non-police issue shoes
2. Dirty Police Uniform
3. Cotton in his ears.
Mr. Wise was one of the police officers who arrested the Three Tramps (Pergola Assassination team).

The casing had apparently been there for a long period of time. This spent shell was found on the area of the roof facing Dealey Plaza.
Opinion:
If Oswald was not the patsy, then the three tramps would have been the patsies.
Mr. Wise, because of the circumstantial evidence, I believe Mr. Wise was the rooftop gunman at the records building. That is why he was dirty with what is most likely to be roof gravel on his shoes and uniform and why he had cotton in his ears to muffle the sound of shots that he fired with his rifle. I, personally do not believe a word of his testimony, it has not been vetted!
Here you can see a reflection of the rooftop gunman in between the sprockets of the Zapruder film frame. The Bell & Howell camera used is known to do this when in full zoom.
