The impact of any crime on society is masked by the inflated stats, and it's also diminished by them because if even some of the false reports are stopped, suddenly there's the appearance that the crime itself has decreased. 1st most rapes are not reported (which begs the question) and 2nd many reported rapes are not actually rapes. So if you looked at the violent rapes, not just guys who didn't stop when she decided she was mad or had second thoughts, it would be even lower. Would that relatively low number lead to fewer dollars spent to battle it? Perhaps. I cannot imagine there are a ton of false murder or robbery reports, although fraudulent insurance claims are no doubt higher than false rape claims.
