So I've seen this pic shared on my FB wall a few times...
Basically it's an anti-rape device that barbs itself onto a male rapist's dick when he try's to rape a female vaginally. Sounds great in theory and all, but...
...could a guy not just slip his fingers inside of the woman's vagina, grab the thing, and pull it out? Or insert something 'sacrificial' into it to remove it. And since we're dealing with rapists, one dumb enough to get this thing hooked on his Johnson would probably go ape and end up killing the rape victim. Just doesnt seem like the BEST solution to prevent rape in my opinion.
