That's irrelevant and not actually true, if you replaced 'physical' with 'direct' then you would be more accurate.
By irrelevant, I mean that people are not trying to convict Jeremy, that's already been done, people are trying to show that he is innocent and that hasn't been done. The fact that you disagree with the evidence put forward during the original trial, in no way adds weight to any argument that he is innocent, unless you are providing contradictory evidence which suggests that something else took place.
