I understand your feelings but it needs to be kept in the context of a business decision. Antiquorum is an auction house, a business, not a judicial organization able or bound to judge a point of law. And that is exactly what property ownership is — issues of law. Hell yeah, if given an "out" I would expect them to go running from the entire issue. Expediency.
Again, that's why the police should have been the first point of contact.
Aside from the reputation of Antiquorum, which has been pretty throughly trashed, it is a moot issue.
