So I see rape, sexual assault and domestic violence and a pretty big problem. And it doesn't go away because it's is broadly tolerated rather than successfully prosecuted against. And that is because it usually boils down to one persons word against another. And often the smooth talking villain sounds more rational and self controlled than the disturbed victim.
SO, although I hate this idea because of the privacy implications, but no one stopped google glass, so why don't we have an app that records everything on a rolling basis, uploading to authorities when suitably triggered, deleting after 48 hrs otherwise? Alexa listens all the time, why can't we make use of that capability to gather evidence?
