To answer your question in a non facetious way, there's a phenomenon called the csi effect. Essentially, juries expect csi levels of ironclad proof that tends to make it much harder than expected to convict.

Combined with the high profile and over politicisation and publication of the case, i see it damn near impossible fornthem to find 12 jurists who will unanimously find not only enough evidence, but not have a refuser based on sociopolitical contexts- much like how OJ walked on the LAPD's corruption.
