Yes, I agree to an extent. It is beneficial to share their experiences in the right contexts. However, they are taking this pretty hard (understandably so given the circumstances.) So, making them relive it psychologically may not be the best thing right now when they already blame themselves. Even beyond that however, there are potential legal ramifications which may prevent them from wanting to share much detail publically right now that the media isn't addressing.Sometimes talking about it and telling the story over and over is a way for people to cope with their grief and get it out there. My cousin lost her four year old daughter in a house fire. She was able to save her toddler twins but could not find the four year old even though she went into the house multiple times trying to get her. The police/fire people finally restrained her and would not let her back in when they arrived. She told her story to us multiple times every time we visited her while she was healing from her burns and such. It was horrible and you never get over a loss like that...ever. Please share our condolences.
In terms of psychology, this was in incredibly traumatic experience. This type of experience can completely alter one's perspective on any number of things in the world. It can be very delicate to deal with.
