At the start of my military career I was an MP. Was first on the scene to a few rape cases. My observations are the same as yours, about 40%-50% of rape cases appear to be false accusations.
Now all our rape cases were investigated by CID and always had a female assigned to them. I was talking to the CID agent on one of the cases I was first on. She had been in the Corps for 12 years. She told me that from her experience about 50% of rape accusations were false.
Yeah. The figures in this article appear to be very much on the low side.
Most of the reasonably executed studies I’ve seen show numbers between 25% and 65% (mostly based on definition differences, and location), with a reasonable center a bit over 40%.
