> but a reasonable person might assume these rumours to be true

From all the claims Afroman made, it seems the cop sued because of the whole "He claimed he had sex with my wife, which reflects poorly on me", presumably because he only has a chance to win the suit if there is actual lies. The same video seems to have texts about how he crashed into civilians, stealing pills/money and more, but none of that was brought up in the suit, only the cheating part.

Although funnily enough, when one of the questioned about if his wife had an affair with afroman he was like "I dunno". If he doesn't know it's a lie, kinda defeats the point of the defamation suit

We are, of course, not privy to the jury's reasoning unless they choose to divulge it.

Which is unfortunate, because we may never know if they concluded "Given who you've demonstrated yourself to be, your wife is justified in seeking other lovers whether or not this allegation is true" or if there were other factors involved.
