@Hyolobrika @thatguyoverthere Yeah, it's common. Here's the most surprising courtroom "moderation" story I've heard (unrelated to this case):

Apparently some judge did not allow an expert forensic witness to "use Bayesian statistics" because there mere utterance of sophisticated stats terminology would make the argument appear more certain than it was, defeating the purpose of stats in the first place.

One reason I fear the court system is that I don't really trust that the "jury of my peers" will really be my peers. Race may cause bias (as you're suggesting), sure, but math illiteracy / general retardation scares me even more. Every time I see some jury member interviewed on TV, it scares me (although there is surely also a selection effect there).
