I think they need to invent vagina inserts with razor blades... totally comfy & safe for the woman wearing it, but rapists? Buwahahahaaa! Only a few women would actually need to wear them, the deterrent factor would be Amazing!
A real part of me hopes that it will be used to stop rapes but the other part of me kinda wants to see some ( insert words here ) go to prison for life because some socially imperfect schmuck had the audacity to believe that he could talk to some socially perfect female.
And then women are charged with assault. But I'd also like to have one. Fire. Awesome.
