BINGO!!!!! I agree 100%.
But the "low crime area" part doesn't matter if you are bringing home new strangers you meet off the internet swingers' clubs every weekend. You may not agree, but I think there is risk bringing new different folks who like to screw strangers into your home every week. Let's face it, swingers who screw strangers an hour after meeting them are not "stable low risk moderate folks". They are volotile high risk personalities by definition.
The people she brought home were people from the neighborhood bar a couple of blocks away. We don't know at this point if they were strangers or long-time friends. What we DO know is that it wasn't some kind of "swingers club".
