I looked at this headline and I thought to myself, that I couldn't think of a stupider solution or a dumber sales pitch than "hey DV victims! use this complex gadget!"

No. I mean, come on. This is the sort of thing where people read a poster in the ladies' room and then they carefully plan a discreet exit from their life of abuse. These are very low-tech escapes. They involve packing your necessities and slipping out while your abuser's not watching.

And yes, the social safety nets, and the institutional protections, are the operational needs here. No gadgets, please.
