This seems to imply that Depp did not abuse Heard, which was not the view of the judge in the UK defamation trial (he ruled that 12 out of 14 incidents of abuse perpetrated by Depp had been proven to a civil standard).
It looks like Heard also abused Depp on at least a few occasions. But there seems to be this online sentiment at the moment that Heard is a compulsive liar and that she did not suffer abuse at all. There seems to be clear public evidence to the contrary.
