So, the $3k were crowdsourced by Burkhart from Depp fans to get the unsealed documents which she then immediately used to slut shame Amber, posting out of context snippets about Amber’s past working in an exotic club.
Neither Depp nor Heard hired a digital photography expert to testify (they hired digital file forensic analysts: not the same thing). IMO this was a mistake on Heard's part - I think they missed a critical piece of information.
