First, a person is innocent until proved guilty
Well, whether they are actually innocent or guilty doesn't change depending on whether they are subsequently convicted or not (or 'case unproven' as they have in Scotland - a great idea) so they may not be innocent until proven guilty ... they have just not been caught or made to pay yet.
They are presumed to be innocent to give them a chance of a fair trial. Jackson has already tried to turn it in a circus (presumably to fit in with the rest of his life) so I think he should take the bad with the good.
