If you're prepared to put someone else in life-threatening jeopardy with such flippancy, you deserve everything that comes your way in terms of doxxing. Assuming she called the police - instead of feigning the action - she's an actual menace to society (for 'African Americans') and looking into her history, or past interactions with the police has merit to see if she's done such a thing before.
People talking about it being such a shame or mob mentality to have what she intended for another to receive blasted right back at her seem to have misdirected their empathy - how about the victim(s) in such instances? How lucky is the guy filming to actually have the means to disprove her hysterical words and actions? What is the likelihood of something happening to him if it was simply his word against hers?
A woman in genuine distress calling the police against a man should rightly be met with assistance posthaste - a white woman calling the police against a black man whilst heightening the threat level via feigned distress, in America, is going to get the works: blue lights, multiple officers in an excitable state, guns un-holstered and ready to mete 'justice' to the supposed perpetrator with an act first ask questions later attitude that is very clearly potentially fatal. Whether her intention was merely to scare him or in full awareness of the potential outcome of the call, she's very clearly someone that needed to be flagged, which doxxing will have done.
By the way she was lynching the dog, one might think it was serendipitous intervention, for its sake!
