they admit they had no idea what he was doing or looking at in his basement isolation.I can't say I blame them. The mother also admits she knew nothing about porn at all, and thought that he was looking at still pictures. This is not surprising considering his parents most likely grew up with exactly that, still pictures and perhaps VHS tapes, not the stuff we have today.
Sure, they could have done a better job, but I maintain the route they took was better than killing off his access (which they actually tried to do, see the comment made by the dad after the story, they eventually realized it was futile, and I think they would have saved themselves a lot of heartache had they approached it intelligently from the start).
And letting the lice-infested homeless craigslist woman come live with them? I can't see any way to spin that as a good idea.
Well, another thing to consider is that a lot was left out from the story. It may very well be they didn't know how he found here.
Again, from the comment made by the father:
And then there is the matter of the homeless woman. Again, we did not simply let
this happen. For months the police, the courts, and an entire team of medical
professionals who were not mentioned in the story were involved. We all agreed,
after months of agony, that the approach we finally took was the least of a
multitude of evils. Everything that happened over this period of time, and with
all of these people, is left out of the story, again, to save Alex
embarrassment.
