More info. The passengers did take action. It seems one passenger yelled, "stop stabbing him, you low life bastardo'!", and upon hearing this, the other passengers became incensed, wrestled him to the ground, and held him until police arrived, whereupon the vigilantes demanded the shouter be charged with hate speech. Cool.;-)
