This presentation did also have an amusing angle: an older white gentleman who let's just say was not especially "racially enlightened" (he went on at length about how people like Eric Garner and George Floyd had criminal records so maybe somehow they deserved to be killed by police) was constantly interrupting the presentation with questions. While I thought it was great that this guy was here and wanting to learn more about issues that may make him uncomfortable, our ranger was not having it and was very short with him. It later came out that he hit on her before the presentation.
