I think there must be cultural differences from place to place.
Here, it would be informally known very quickly if a member moving to the area had been in jail for some reason, and people would like to find out why in order to make sure they would not be targeted, be it economic matters he/she was jailed for, violence or whatever. Just as one is a bit careful when one knows another person has mental problems that might turn into violent behavior.
Our friends told their congregation what had happened to the family member in question, who had done it, when, how etc. - and received 100 % support by everbody, from the "top" to the "bottom", not one negative comment (indeed, how could it be!), and so I am very much surprised to read that someone here claims she was threatened with df'ing because of telling. Our friends were hailed - and the friends of the offender were more or less frozen out because of their friendship, and also officially reacted against.
The picture is varying from place to place. Generalizations are not that easy to make. And things are happening so fast in these matters that what was a general reaction a few years ago, are now only the reactions of a few sidetracked hardliners who have not given notice to what is happening in society or in the congregations, much like the East European leaders who fell in 1989/90. Any JW with a capability for thinking will react in the only decent way there is to react to such matters - and the hardliners will be sidetracked to where they can do no harm.
But is the US different? It seems to me so ............. "old-fashioned".
