Reading the discussions on Zimmerman, and seeing the ubiquitous use of this term as the litmus test (by the MSM mostly) for whether he was justified (excepting of course the recent revelation of self defence, now that the police report pdf is readily available and it's debatable whether the voice on the tape calling for help was Martin or Zimmermarn), and given that this should be considered a case of self-defense and not standing your ground (the opportunity for egress already having been eliminated, if he were on his back getting has face punched in), and knowing that the case has become a potential crucible for the stand your ground laws, I have never seen it answered:

How did the relevance of this law, "Stand your ground" become synonymous with the outcome? Was it latched onto by the media and it became a running talking point that some felt obligated to refute? What makes this a test of the law, aside from a few people uttering it within the same breath as the case within the reach of a few microphones?
