Did he do it?

In the beginning I really believed OJ Simpson did not murder his ex wife or her friend, but over time and as evidence kept coming in, I thought well, theres no way he did it with all these cops tampering with the evidence, or because when he did the glove demonstration the glove did not fit Oj's hands at all. During the middle of the case I started to feel as if he was innocent due to lack of evidence and reasonable doubt, even though we knew nicole had been beaten and abused by OJ in the past. Now I believe he did do it, since he had a cut on his finger he couldn't explain, or him saying he disliked the shoes he happened to owned and that were super limited edition, and as well as not having someone with him during the time, he claimed to be taking a shower and not hearing his driver outside ringing the bell, but in my perspective we'll never know if he actually did it or not, because they never did find the murder weapon or did anyone see OJ himself in her house, only way we'll be able to find out if he did do it or not would be if he openly admitted to doing it.
