Nobody was lynched here so anti-lynching law would not apply. Given we're discussing mobs getting riled up over the wrongs of the "other", it also seems appropriate to place the actual outcome in a less exaggerated way.
Kind of ironic that people are getting offended over my choice of words here, but we could call these anti-mob or anti-bullying laws instead. The point remains, it might make sense to make it illegal for institutions to fire people over the call of a mob.
