The absence of physical evidence always favors a defendant, no matter their sex or the crime they are accused of. Bias definitely exists in the judicial system, but in so far as a lack of evidence is concerned this bias will take the form of its absence favoring certain defendants (i.e. white vs. black, male vs. female) more than others. Regardless, we need to focus on fostering a system that encourages assault victims to come forward quickly so evidence, if it exists, can be quickly collected and analyzed. It will always be true, even in a system completely free of bias, that no or very little evidence favors the accused.
