At the end of the day, not guilty. The final disposition of the case was that the charges were dismissed. Two separate juries found him guilty, but ultimately both of those verdicts were overturned on appeal as the result of prosecutorial misconduct in withholding evidence, amongst other things. All persons are entitled to a fair trial, by an above-board prosecution that reveals all of the evidence, exculpatory and otherwise, to the defense. The prosecution did not do that, not once, but in two separate trials. Folks can debate whether in fact he actually killed anyone, which is another question separate from the question of whether he is legally guilty.
GUILTY! I grew up in Paterson and I knew Carter and his partner in crime, John Artis. In fact I lived a couple of blocks away from the Lafayette Bar where the murders took place. I first met Carter when he came into a ball field in Paterson, called the Riverside Oval." I yelled out his name and he turned and waved. Later on he and a couple of his friends went across the street to a bowling alley, so me and a friend of mine followed him. As they started to bowl and Carter asked me if I knew how to keep score. I said I did, and he invited me down to do so. After that I would see him again at the Oval and he would actually pitch softball for one of the local teams. If he saw me, he would say, Hi Kid, why don't you sit down with us, so I sat with him and his teammates on the bench. When I was in High School back around 1967, my teacher asked me if I would like to go to the court house for a couple of days and follow the case, which I did. I followed the case very close, because I really liked Rubin, BUT when I heard the whole story, I was sure that Carter and Artis did the act. In the movie they had a cop that would try to frame him, I know a lot of people that knew that cop and he was one of the best and honest cops around.
