Attorney: I ask you to find Mr. Smith guilty of assaulting Mr. Jackson.
Conclusion
Mr. Smith is guilty of assaulting Mr. Jackson.
Intermediate Conclusion (colon)
Mr. Smith has a violent character.
Evidence
Ms. Lopez said that Mr. Smith shouted loudly and threatened her. Smith never refuted this testimony.
Evaluate
Since this argument involves two conclusions, we need to examine both reasoning moves.
Given that ... Ms. L says that Mr. S shouted loudly at her, threatening her, while Mr. S never refuted this, Should we accept that ... Mr. S has a violent character?
Of course not. First of all, one instance is not enough from which to draw a conclusion about character. We all have some days where we're very snippy and short with people because of other stresses going on in our lives. So maybe Mr. Smith shouted threateningly at Ms. Lopez because he was in a terrible mood that day or badly stressed by something, but this out of character for him.
Moreover, the fact that Smith never refuted the testimony isn't an admission of guilt. I don't think Hillary Clinton ever refuted the Pizzagate allegations (there was a conspiracy theory that she was running a child trafficking ring out of the basement of a pizza parlor, back in 2016). Sometimes people don't respond to what they consider groundless accusations: "I won't even dignify that with a response". That doesn't count as an admission of guilt. The 5th amendment protects a witness's right to stay silent.
If we accepted that ... Mr. S has a violent character, Should we accept that ... Mr. S assaulted Mr. Jackson?
Of course not. There are probably hundreds of NFL players with violent characters. Does that mean that they all assaulted Mr. Jackson? We would clearly need more evidence.
Goal
Look for an answer complaining about the move from "He threatened me / never refuted it" to "He has a violent character", or an answer complaining about the move from "He has a violent character" to "He assaulted Mr. Jackson".
