What have they got to lose?
They have no jobs, their grandadughter is dead, their daughter is a murderess and will possibly be executed for her crime.
They must look back upon KC being a toddler, a cute bundle of fun (Hey - who remembers the tantrums - not me).
They now LIVE in memory lane, their recent past is painful, their present day is dismal, and their future contains jail visits and death row.
Why would they NOT say these things? Facing what they are, I'm not sure I'd give two hoots that a bunch of strangers didn't like me.
REWIND.
Actually, I'd have been more honest, more open and hoped the public would understand. After all, my childs life would be in their hands soon.
