> Not all reports classified as unfounded are necessarily false. In some cases, women who were victims of rape were disbelieved, pressured into recanting, and charged with false reporting only to be vindicated later on—the kind of awful story that adds to people’s skittishness about discussing false accusations. Some police departments have been criticized for having an anomalously high percentage of supposedly unfounded rape charges: Baltimore’s “unfounded” rate used to be the highest in the nation, at about 30 percent, due partly to questionable and sometimes downright abusive police procedures, such as badgering a woman about why she waited two hours to report a street assault. By 2013, an effort to provide better training and encourage full investigation of all complaints reduced that rate to less than 2 percent.

The problem is that you cannot rely on a police officer's opinion that a rape accusation is false. It could too easily be based on a sexist perception of the woman reporting the crime. The rape of sex workers, women who use drugs and alcohol, and women who have many sexual partners has never been taken as seriously by law enforcement.

On the other hand, we have actual scientific data from the CDC showing that 20% of women have been raped: http://www.cdc.gov/mmwr/preview/mmwrhtml/ss6308a1.htm?s_cid=...

What we need is an equivalent study that asks men if they have ever been falsely charged with rape. My guess is that the number is quite small.

"Some women don't make false rape accusations" -- true. My mother is a woman who has never made a false rape accusation. So is my wife. That's some women who don't make false rape accusations.

"No women make false rape accusations" is what you probably meant to say. That's demonstrably false -- some women do.
