False allegations are far from being fantastically rare.
You also have to acknowledge that when you have a rape accusation, there isn't a boolean result(either the allegation is false, or it's true and this results in some penalty). It's a broad spectrum, with only around a third of the cases resulting in conviction.[1]
Of the 136 cases of sexual assault 8 (5.9%) were coded as false reports, 61 (44.9%) did not proceed to any prosecution or disciplinary action, 48 (35.3%) were referred for prosecution or disciplinary action, and 19 (13.9%) contained insufficient information to be coded (see Table 2).
