Consider this:
The United Nations says South Africa has the world’s highest per capita rate of reported rapes – 119 per 100,000 people. Analysts say the total, including unreported rapes, could be nine times higher.
Then consider the device in question: an internal “trap” designed by a South African medical technician to thwart rapists by sticking barbs into their penis upon entry. All kidding aside, I think the upper hand this gives women during a rape far outweighs the criticism proffered in this article. It will definitely convince people to think twice, even if its mere existence acts as a deterrent.
