OK.

In the civil case, OJ was found "criminally responsible". That says he did it.

Him being found Not Guilty of First Degree Murder does not prove his innocence. In First Degree, you have to prove premeditation.

There are different ways to charge someone with murder. If he had been charged with Second Degree, or manslaughter, I believe they would have had a criminal conviction, as different standards are used in those charges.

He is guilty of killing them. He is not guilty of First Degree Murder.

PS - In spite of the civil case findings, he has not paid a penny to the Goldman or Brown families.
