Now I'm very fascinated by this thread and I want to jump in, so thank you.

I would like to make a few points: 1. I think that the limitations of where you can invite a vampire into are scoped to where you reside, that is, the indoor location that you own or that you rent that you are currently occupying. 2. A warrant is not an invitation. A search warrant, for instance, gives authorities the ability to legally enter a location for a specific purpose where they would otherwise be unable to. In the case of a vampire cop they would legally be allowed to enter but physically unable as there was no invitation. 3. The only case I can think of where things would get murky (kind of) is in the case of a legal seizure of property. In that case a vampire would be able to enter, however, because the property was seized it no longer serves as the residence for the individual and so there can be no invitation in the first place.

And so I would maintain that any vampire, regardless of occupation, would be unable to enter a potential victim's residence. If there were a vampire judge who could issue a seizure of property, that is a potential loophole that would enable a vampire to confront a victim.

Also I'd be super down to continue this conversation.
