That's just TOO convenient a question to ask before the guy you're asking is shot and killed.

Is it, though? You kind of have to consider the subset of debate questions people are likely to ask Charlie Kirk. If you ask a random guy you run into in the grocery store "are transgender people unusually violent" and then he gets shot by a transgender-adjacent political activist, yes, that's a wild coincidence. If you go to a political debate event where the person you're debating is a Christian who is outspoken against transgender ideology, outspoken in defense of the second amendment, and there was a transgender mass shooting at a Catholic school in the last three weeks... I imagine that he'd probably already been asked a couple questions near that subject, and that if the event had continued, he'd have been asked a couple more.
