Contemporaneous report of abuse to others absolutely does bolster her argument that she didn't just make it up for the divorce.Amber just used the therapist's notes argument again. NBC's team looked at some of the notes too and noted that there claims of physics abuse going all the way back to 2011. I hope people realize that the notes of the therapist are essentially minutes of a meeting and it doesn't legitimize the content of the notes if they're writting by a therapist of a construction worker for that matter. It's notes that describe something that Heard is telling, therefore hearsay.
But again, this isn't a silver bullet. Depp's lawyers had better time management, had these notes came in, they only needed an hour tops to show that Heard has a habit of claiming to be abused in instances where she's the abuser. Look what you made me do sort of shit... Leaving the fight she started is hurtful to her, etc... Or they could play the tape when he asked her if she believed she never abused him and rather than say she never did she is silent for a bit then talks about being 115lbs and have never managed to knock him off his feet.
