^* this case is not about proving if AH was an abuser - but disproving JD was an abuser, which he will never disprove.
What evidence do you need exactly before you believe her? Is it the same level of evidence you need before you believe JD?*^
But the title of this thread is "anyone watching Amber Heard take the stand" and the OP is "I'm not sure what to think" which is why im talking about AH and whether i believe her rather than whether or not JD will win the case.
If a friend, neighbour or colleague told me their partner was abusing them, and then showed me loads of photos and videos as evidence but none of them actually showed any evidence of abuse I would find it hard to believe them, especially if the footage and voice recordings actually seemed to indicate that it was them that was actually abusive. That doesn't then mean, that I automatically believe anything their partner says, it just means I don't believe them.
I know of someone who accused her boyfriend of punching her several times in the face and giving her a black eye, her proof of this was to show a picture of her broken phone case and broken false nails. She's also posted on fb 2 days after the "incident" and must have had very good makeup on to cover up the black eye.
