Trump is good at controlling a crowd, I hear what he says to egg them on - "In the good old days they go out on a stretcher" - "I'd like to punch him in the face" - :If anyone sees a protester, knock the hell out of him" - "I'll pay the legal fees" - All done on the microphone during protests. IMO, that is inciting a riot.
Non-violent people cannot be *incited* to commit acts of violence. This is no different than when someone listens to a song, reads a book, watches a movie, etc. and then makes the claim it caused them to commit an act of violence. IF someone responds violently to words, it is because they are already a potentially violent person.
