I understand where you are coming from but......................family is looking for closure, a reason why it happened, someone or something to blame, and eventually the truth if it can be found.
Most of the time, family members know everything may not be rosy, but they want to know something, good, bad or otherwise. Like I said before, someone making completely unfeeling and crass statements that do nothing, should be addressed.
I just think that we (SB forum members), unknowingly, don't give family members the credit they deserve. They already know a loved one has died (the worst outcome). Now they would like to find some answers if they are available. Not knowing is the worst thing after a major incident of any kind. If nothing else, the family will see that we are also trying to make sense of what has happened as it could have been "me". I truly believe this does more than we will ever know, for those that have lost someone, until the day that we are that family member.
