As a matter of fact, some people do wait around for moments when they can get away with violent crime. I've met them and this is how some people think (maybe even most violent people are this way). During one weekend of the protests in Chicago this summer, there was a weekend with over 20 murders, which happened partly because people knew all the police were downtown and it was a good moment to settle scores (https://www.bbc.com/news/world-us-canada-52984535 https://www.bbc.com/news/world-us-canada-52984535). I agree with you this could have something to do with the rhetoric you mention, just as well as other political rhetoric. It could also just have to do with virality, the impression of lawlessness/lack of repercussions, the "fun" of being violent, and people in public who shouldn't be. In the end, if you shoot a woman in the head with a flare gun, I'm not too concerned whether you claim you did it because "of the president's rhetoric", "to fight white/asian supremacy", or "to steal her pocketbook for economic motivations". I'm more concerned that the police arrest you and the government locks you up until you know better. Anything else looks like more deflection of responsibility to me.
