This isn't how sets work. Elements in a set do not "come out of a set" just because they are part of a subset. Being within more than one set is the very definition of being in a subset. If you're going to conduct an impromptu GCSE Maths lesson, at least make it an accurate one.
@Andersonson was making the point that crime rape has a low conviction rate. You then reference the subset of rape cases that go to trial. Seeing as we seem to be so interested in subsets, when we consider the ones we could create from the CPS process:
- Incidents
- Reported incidents
- Reported incidents leading to arrest(s)
- Reported incidents leading to arrest(s) and charge(s)
- Reported incidents leading to arrest(s) and charge(s) and prosecution
- Reported incidents leading to arrest(s) and charge(s) and prosecution and conviction
If the figures in sets 1-4 are high (which they are) it becomes obvious that the relatively high (
though still lower than other crimes) prosecution rate for cases that go to trial isn't particularly relevant to the point that the conviction rate for rape is low.
It does have relevance to the analysis of Mendy's case, as he is within that subset. Also relevant are the points you bring up about the evidence his defense provided of contradictions and collusion within the prosecution's case. Judging from the information that has been made publicly available, I think I likely would have voted 'not guilty' had I been one of the jurors. The burden of proof lies with the prosecution, so I would have to vote to acquit - even if I had doubts about his "innocence".
The presumption of innocence is about giving people in Mendy's position the benefit of the doubt. It's not about empowering thought police to shout down the opinions of those that have may still harbour those doubts.
