Truthers are seriously delusional at the best of times, so it is not surprising that they are also despicable ghouls, lowlifes and scumbags when it comes to the deaths of others.
Let me put this in perspective. My brother died on December 2 at the age of 51. You - truthers - are not entitled to know anything about him whatsoever, his place of birth, his place of death, his cause of death or anything else. You wouldn't be even remotely interested in his life, never mind his death, unless you thought you could exploit it for your own purposes. If I told you that he was at the World Trade Center on September 11, 2001 (he was not), you might suddenly become interested in his death, but only if you thought it would promote your paranoid conspiracy fantasies.
A friend and colleague died three days ago on December 21 at the age of 47. You - truthers - are also not entitled to know anything about her whatsoever, her place of birth, her place of death, her cause of death or anything else. And you wouldn't be remotely interested in it unless you thought her death would somehow further your conspiracy fantasies.
So what makes you think that you are entitled to know the personal circumstances of Barry Jennings - who was just a guy going about his life, with a family, and whose family has no reason whatsoever to share personal information with you?
Just stop it. You're nothing but ghouls. And despicable ones at that.
