I guess at least that means someone will be aware of the interaction and the copper would have to be fucking stupid to try anything. But really, if it hadn't been for this tragedy, it's not the sort of thing anyone would think to do.
Not quite as evil - although close enough - but I remember reading about similarly missing-the-point type victim blaming in 2008, 2009. There was this guy in London posing as a landlord and scamming money from people. He'd break into an empty flat, advertise it on Gumtree, show people round who would fall for it because he actually had a flat to show them. The widely known version of that scam at the time was the "Please send the deposit amount to yourself via Western Union and then forward me the receipt" where the scammer makes all these bullshit excuses not to meet you, but I think that was one of the first publicised case where the scam didn't happen that way. Anyway, similarly missing the point, some idiot detective appeared on the news to lecture renters about how you should "Always view a property before you hand over money!" They DID! The flat existed all right, it just didn't belong to him!
Yes, reading about that did make me more vigilant about checking the landlord's details on the Land Registry when moving somewhere, to make sure the name matches. But unless I'd been aware of that sort of sophisticated rent scam, where the perp goes out of his way to make himself believable, why would you think twice?
