Microscopic Hooks For Bad Fish

Click on the title for a link to a London Times story about a device - more on the controversy surrounding the device, actually. The device is made for a woman to wear and, in the event of her being a victim of rape, the device attaches to her attacker's penis with microscopic hooks. The attacker will not be able to remove the device without medical assistance. I have no clever comment, just fascinated with the story, both the device and the debate.
