Usually good. Fun part, though, is that doing ad hominem fairly would find all the times the FBI, DOD, CIA, NSA, and so on mislead the public or courts. Then, their credibility would be at zero just like some conspiracy nuts. Then, moderates like myself would win by default given we're the only ones presenting, but not forging, evidence. So, I tell them to bring the character assessments on but apply them fairly and equally.
Evidence was elsewhere. You know where to find it. You had already dismissed the whole topic with an ad hominem with plenty assumptions and no references whatsoever. If anything, I acted above your standard of discussion. I've replied in another comment with more details focusing on just one angle from government docs and activity only.
