OK young un.
Well OJ was found not guilty because "If the gloves don't fit, you must acquit", the defence created enough "reasonable doubt" for the prosecution case to collapse. The family of Ron Goldman took out a civil case against OJ after he was found not guilty.
The standard to be found liable for the deaths of Ron and Nicole, was lower a preponderance of evidence, i.e. most of the evidence supports that OJ was liable, a lower bar to clear. He was ordered to pay 8.5m in damages, probably about 18m in todays money. It cleaned him out, and he ended up getting involved in other dodgy crap and going to prison for that.
If somehow, this officer is found not guilty, you can see the same thing happening, he will be financially wiped out by a civil suit.
