Except that by some estimates, only about 3% of rapes ever result in a criminal conviction. I wouldn’t vouch for that exact figure, but people who study these things would agree the percentage is extremely low. Half or more are never even reported to the police, either because of fear of retaliation by the rapist, or the victim is (or has been) in some kind of relationship with the rapist and doesn’t want to see the rapist prosecuted on felony charges, or doesn’t want to go through the usual “blame the victim” interrogation by disbelieving police and prosecutors, or doesn’t want to re-live the trauma of the rape before police investigators, prosecutors, and an open court, or feels there’s too much stigma attached to being raped and just wants to keep it quiet, or simply doesn’t believe it would do any good to report the rape to police because so few rapes ever get prosecuted and even fewer get successfully prosecuted. Consider all the women who have recently stepped forward.and said Bill Cosby drugged and sexually assaulted them. How many of them reported those incidents to the police? Precious dew, if any, and so far as I know, none ever resulted in a criminal prosecution. And so, if the allegations are true, Cosby apparently believed to continue to drug and sexually assault women with impunity. Why didn’t they report these incidents to the police? They all say they thought no one would believe them, there were no witnesses, and/or they were at vulnerable points in their careers and thought someone as powerful as Cosby could retaliate and destroy their careers and reputations.
Even when sexual assaults are reported to the police, in many cases the prosecutor won’t bring criminal charges because without eyewitnesses it becomes largely a “he said v. she said” situation, not a winnable case when the standard of proof for a criminal conviction is “beyond reasonable doubt.” DNA evidence only establishes that there was sexual contact, which most rapists won’t deny (most rapes are committed by someone known to the victim), and even bruising or other evidence of physical abuse isn’t conclusive because the defendant can claim it was just consensual “rough sex”; moreover, rape isn’t always violent. Consider the college student who drinks at a party until she passes out and then is sexually assaulted. Or the Cosby-type situation. For similar reasons, even when rape cases are prosecuted, all it takes is one skeptical juror who might even think it’s more probable than not that the accused is guilty, but thinks the prosecutor hasn’t proved it “beyond reasonable doubt,” and the jury will fail to reach a guilty verdict insofar as unanimity is required.
I know some people will say that it’s precisely because rape is so difficult to definitively prove that we should leave it to the criminal justice system, so people falsely accused are not punished for offenses they didn’t commit. That’s why we have such a high burden of proof in criminal cases; we don’t want people to suffer criminal sanctions for things they didn’t do. By setting the bar high, we avoid those “false positives,” at least most of the time. But we also pay a heavy price for that, especially in the context of rape, because it means the vast majority of actual rapists go completely unpunished. I’m not suggesting lowering the bar for criminal convictions. I am suggesting that for lesser sanctions, like suspension or even expulsion from an educational institution, or “no contact” orders on campus, setting the bar at “beyond reasonable doubt” and only after the full criminal justice process has played out will effectively guarantee that most campus rapists pay no penalty at all. Another or additional alternative, I suppose, would be to encourage more victims of sexual assault to bring civil lawsuits against their attackers because then the standard of proof would be “preponderance of the evidence,” i.e., “more probable than not,” rather than “beyond reasonable doubt” as in a criminal prosecution.
