I thought it was really interesting that we saw so much of the politics in SB. It's obvious that dhampirs don't get told enough about them. Maybe Rose missed some instruction on the political aspects of life in one of the two times she wasn't at the academy, but to me it seems like the dhampirs are only educated in fighting etc. So it was interesting to see just how they pass certain laws and further aspects of how they deal with rule breakers.
I don't think it's fair that the Moroi have control over the dhampirs though. Even if Tatiana (or some other moroi) was the Queen/King, I think dhampirs should have their own government, not just their own punishing system and records. It'd mean they have their own voice on matters that involve them.
