Well, yes, actually.
A landlord can be held responsible if they persistently allow criminal activity on their land - I know of one local case where someone was prosecuted for it (turning a blind eye to a canabis cafe in their premises).
Primary responsibility lies with the tenant of course.. just as in ebay primary responsibility lies with the seller. OTOH in ebays case they're just pretending that this stuff doesn't go on *and* profiting from it (profiting from crime is itself a crime btw.) then yes they need to sort it out.
It is never the responsibility of the victim (tiffany's) to investigate crimes against, themselves, as the previous judge seemed to believe.
