Sorry for the ambiguity, that's not what I meant. I was trying (and apparently failing) to say that one system does not invalidate the other, in either direction. It is frustrating, distressing even, when a likely criminal escapes prosecution but I don't believe that this represents a problem with the core principles of the justice system. If anything, lowering the standards required to secure a criminal conviction would be more harmful to women in particular because it would likely result in more women being convicted of giving false statements in cases where those cases were dropped due to insufficient evidence. This would, in turn, further discourage reporting of incidents in the first place.
