How did the criminal and civil cases involving O.J. Simpson have different outcomes?

The differing outcomes in the O.J. Simpson cases stem from the fundamental distinctions between criminal law and civil law in the United States.1

In the 1995 criminal trial, Simpson was charged by the state with murder. To secure a conviction, the prosecution was required to prove his guilt "beyond a reasonable doubt," a high standard of proof intended to protect the accused. The jury acquitted him, meaning the state failed to meet this rigorous threshold.2134

In the 1997 civil trial, the victims' families sued Simpson for wrongful death. Civil cases differ significantly from criminal proceedings:56
* Standard of Proof: The plaintiff only needs to establish liability by a "preponderance of the evidence," a lower standard than in criminal law.21
* Purpose: While criminal law seeks to punish offenses against the state, civil law focuses on compensating private parties for injuries.1
* Outcome: The civil jury found Simpson liable for the deaths and ordered him to pay $33.5 million in damages, a financial penalty rather than the imprisonment associated with criminal convictions.31
