But this place isn't normal in that what you want to do is always under your control. You personally experienced this recently. Yes, anyone can be evil and hurt or kill someone. Not everyone has the capability to change a life with a whim into something they did not ask or wish for. That power alone is a danger in this sort of place.
Vampires add an entirely new level to the food chain for humans. It's not comparable to anything else because of this reason. Even if you choose to not partake in human blood, that doesn't remove you from the food chain.
I personally would rather the list be on a need to know basis for emergency situations. The whole of the defense force, I don't think needs to know. But anyone willing and able to engage in any issues dealing with vampires or hunters needs to know who everyone is.
