To be precise, I'm not faulting her or saying she should have "done a better job." Earlier, I posted that I think there is a neurological inability to rapidly figure out the situation in ORDER to communicate its urgency - that is, the mind of the sane person cannot possibly anticipate the plans of the murderous psychopath - unless they are looking for it.
That's why, on his behavior cited in his parents' divorce papers, his status as a "person of interest," his wife's disappearance, and the images on his computer, he should never have had home visitation. The social worker's shock prevented her for anything other than the puzzled response she first had. You can hear her anxiety rise but it can't keep up with his actions because he had the jump on her.
That is also why I think the situation alone - the door closing on ANY supervised visitation, even one with a nonviolent perp - should IN AND OF ITSELF constitute an emergency. If it did, she would have had a hand-delivered response that would have ASSISTED HER.
I don't know if that makes sense - I am trying to suggest a way that no one social worker or court supervisor in the future will have to go through this and be in their position, because they will have a mental code that overrides their shock and assists them in getting help.
One last thing: outdoor wilderness training has such codes. One is STOP: stop, think, observe, plan. People must deliberately train themselves to use this series of actions because neurologically, when lost, our brains lead us to go on and on and on....and this is how we get lost. So wilderness training gives us a mental code to use to override our "animal" brain.
