Video of the sucker-punching that happened in Fayetteville at a Trump rally: https://youtu.be/2LX4Q643aEU.
The Trump supporter charged with assault in that incident later said on camera that "next time we might have to kill him." That video has disappeared from YouTube.
A couple of weeks at one of his rallies in Las Vegas, Donald Trump himself was strutting for an audience, saying about a protestor that he'd like to "punch him in the face."
Violent rhetoric, violent behavior.
