I was less concerned with the killing sprees than the Rape spree, but it was after the open letter from Julius to the rulers that it would stop that it continued into Grodno for 2 days.
Edit: Good to know the 2nd noble was Banished - nothing was ever said to Luria about it. I've seen more information from random Barcan/Fissoan/D'Haran nobles than i have from those I've asked directly.
Rape is not reported to the realm doing so, only killing, so they actually didn't know rape was happening until you said something.
