Totally agree this should be in that list for new comers. I am not making any judgements or claims about this individual case; but feel that this should be an eye opener for many of us in this forum because our diaspora is growing and many of us either already or soon enough will host our ailing (or fit) parents here in US and obviously they'll go for a walk. Also communicate about a Guy jumping from the bush with a dagger and saying "Gimme all u have". These both uneventful scenarios should be discussed and thought about.
Once again 'no comments' about this particular case.
