Except to the law, which is the ONLY thing that matters, as he hasn't been charged (or convicted) with any offence. Is "trial by Social Media", where non-legal opinions count more than the law, a thing you'd like over the current system?
No, not except to the law at all. That would be up to the CPS to decide the likelihood of a conviction, then a magistrate (if charged with common assault) to decide.
However it is clear that many people think what he did is unacceptable.
