Anti-rape Devices

I never knew that such things existed, until tonight. A woman from South Africa, named, Sonnet Ehlers, came up with the concept of an anti-rape device while working in a clinic, during which time she saw countless rape victims. One of her patients said, “if only i had teeth down there”, which gave her the idea.

"The Rape-aXe is a latex sheath embedded with shafts of sharp, inward-facing barbs that would be worn by a woman in her vagina like a female condom. If an attacker were to attempt vaginal rape, his penis would enter the latex sheath and be snagged by the barbs, causing the attacker excruciating pain during withdrawal and giving the victim time to escape. The condom would remain attached to the attacker’s body when he withdrew and could only be removed surgically,[4] which would alert hospital staff and police” <source>

What do you all think of this? some people call it, “vengeful” and “medieval”. lol
the thing that bothers me is that people would have to be wearing that thing all the freaking time, just in case.
