I can certainly see how one might feel that in Mr. Alvaro's place he would have gone to greater lengths. Some of the reasons I think those who felt something was amiss did not act on that feeling is that a) as has been posted here, we tend to second-guess our own intuitive sense of things when the scenario is so extreme it appears incredible b) the neighborhood had an aura of security given by its prosperity, lack of much crime, presence of local and even federal LE c) the boss is the boss and a trustworthy guy so one does not want to over-react or challenge what he says is going on d) do many others in the life of this family, neighbors, workers in the home and the business, that it would be hard to see them as potentially isolated and at peril. It's been demonstrated that if smoke is filling a class room, students don't immediately act; rather, as long as several peers remain calm and don't seem to see the smoke, they think things must be normal. Same sense of everything must be okay prevails when we hear a scream in the night, but we live on a fairly busy street and our neighbors don't react, no sirens, no more signs of danger, so we assume the scream was a mock scream, a cat.,..I think folks around this family trusted they were safe, canny, vigilant, competent, that Savvas had things under control at all times. What makes the family's story so newsworthy is how unimaginable it is. To think that in such a secure setting, given the time of day, numbers of workers in the yard, in the house, at various times, dogs (who could at least bark), proximity to other houses and the street, general atmosphere of care/vigilance due to embassy and church and school and prosperity and politicians...it was all unthinkable that this happy household could be undergoing gruesome horror while the lawn crew manicured the front yard and retrievers frolicked in the back. Unfortunately, more than one person did get "a feeling," but simply could not believe it.
