Do you know that he had his FB set to private? If not, he WAS advertising SS's possessions, whether intentionally or not. A friend of mine who gave a very expensive wedding for their daughter was infuriated when someone posted pictures from the event.
It's an invasion of privacy. IMO. Post your OWN stuff.
As far as being friends with AS and PS..do we know that his posts appeared on either one of their timelines. I have "friends" and I have no idea what they are posting.
You are correct that he is not hungry for "media" attention, certainly not now after he has been "witness-shamed" by an official document from LE. I stand corrected as to NOW. But before the crime, he seemed very desirous of any attention he could get...he was a self-promoter (not that's there's anything wrong with it ) but I found the hyberpole disturbing.
But ...we shall see. I certainly could be wrong.
It is particularly disturbing that LW posted such photos of the family vehicles and one of those vehicles is tied to their murder. Didn't LW list his job at the track as being "media relations?" That's an indication to me that he WANTED media attention and LE gave it to him by the witness shaming.
