The old fashion way...? Police groups don't normally go around profiling everyone they are trying to protect.
[A sort of group of police...] I think, overall, if you wanted a group meant to police the vampires-- the majority would probably prefer that it be policed by other vampires. [The formation of a group like that, though, isn't her biggest concern of the night.]
I feel that by forming and agreeing on the laws themselves, it'll help protect everyone. If someone breaks one of the laws, then they are someone who definitely needs to be policed.
