Anyone have any evidence that suggests this is because there are fewer juveniles that should be in prison, or if we're imprisoning more accurately, or there are more juvneiles that aren't in prison but should be? There's a lot of nuance here and I haven't found any good data on what caused the change -- just political bloviation

Another reference showed "peak juvenile incarceration" at ~100k kids, and 2000 cases were identified in this scandal alone, so 2% of the peak population were touched directly - and this was the most publicized incidence.
