I'll snipe you a bit harder. In the event of a hung jury, the case can be retried (aka the distribution resampled). Practically though, no prosecutor wants to redo the same case over and over. So its safe to assume that 2 hung juries is as good as charges dropped.

I'm glad you enjoyed this problem, both as a riddle and as a neat demonstration of how a societal system can be better (more fair, just) than the underlying society that builds it.
