The shit on his bed i can confirm, there's pictures of human shit on Johnny's side of the bed from when he went out. The cleening lady sent him that photo. There was also his testimony. Her excuse was that it was their little dogs shit, two small fucking dogs that Depp has for many years, so he knows what their shit looks like.
The finger thing is still in doubt, both sides saying it's the other.
Depp says Amber throwed a glass bottle at his hand that was resting at a counter, that's why his finger got fucked.
Amber says Depp had a mental breakdown + blackout and cut his own finger.
We have no way to be sure, but to me Depp's story looks way more believable with the evidence shown, imo, but i'm not the carrier of the truth.
