@SeattleTW The ABC said as much in its statement. I can’t find the written statement but I have found statements about what it contained.
The witnesses also described him as being tackled. Not a single person has come forward and said anything other than that. I think we can safely say that it is a fact that he was thrown down.
Edited to add: I found the actual ABC statement.
Unless they pistol whipped him it is impossible to suffer injuries like he did without being thrown to the ground. You can argue whether or not he did something to provoke the officers, but you can’t argue that the “facts” show he was thrown to the ground.
