It was precisely because he wasn't aware of the full facts that he used the term "maybe". He wasn't making a statement of fact, he was merely speculating on the possibilities in the absence of the knowledge of those facts.OK - let's leave it there.
You gave your opinion that 'maybe' the police officer instigated the trouble, and had her nose broken without knowing the full facts.
Even those who were speaking in support of the police before the second video was released were speculating on the possibilities without knowledge of any facts.
There is therefore no moral highground to be claimed by anyone despite what the second video subsequently revealed.
