I've seen Trump's speech and I have read it. In my opinion, especially considering the context, it was an incitement to violence. The speech itself, despite it being a disaster has oratory, is actually fairly but not convincingly ambiguous. It contains a great many words and phrases designed to rile people up and make them angry and then it has what amount to token phrases and words about being peaceful. It is very much a wink, wink hint, hint sort of speech. What Trump was trying to do was preserve plausible deniability by mundane phrases and words about being "peaceful" while wink, wink, hint, hinting about violence.
The peaceful crap was mere pro forma to preserve plausible deniability which the audience quite properly disregarded has what Trump really wanted to happen. Trump and his acolytes in the media are using that to throw rioters under the bus and deny Trump responsibility.
Oh and Trump's behavior while the mob was storming the capital and the very long delay in getting help to save Congressmen and Senators etc., from assault and possible death is the clearest indication that what happened is exactly what he wanted to happen. There are also indications that Trump appointees and others deliberately weakened efforts to provide security before the attack. To me it looks very much like Trump was indeed trying to incite an attack.
