It is relevant because of the history of violence on homeless people nationwide for forever, and the rich getting away with, well... Murder.  Homeless people are finally being thought of human and efforts are finally being taken to give them advocacy and a voice.  Homeless people aren't always victims, but they are uniquely susceptible to victimization because of physical and mental health issues among other disabilities.  But, the overriding vulnerability is their social status.  "Who cares about the homeless?" is often been the feeling in the United States.  Just look where her daddy is practicing law - Texas.  It wasn't too long ago that Dallas was trying to literally force the homeless out of their precious city because, "Eww, the homeless are ruining our city!". When someone from a historically disadvantaged and victimized group is shot under suspicious circumstances, everything is relevant. I don't know the whole story here, but the outcome doesn't jibe with the circumstances.
