It’s possible that the family is keeping quiet due to a number of things that include, paid off, blackmail, threats, or someone whispered into their ears that he was working for the CIA and it’s a matter of national security.
All of the above sounds very reasonable given all the lies.
Then WHY didn’t they do that with the other guy’s family, sadly I forgot his name, and HIS MOTHER wants answers???hmmmm...You may be right, but I’m sticking with them being Liberal Democrats.
