I am sure you all know this, but
Clint was set to take a polygraph,
but when LE declined to offer him full
immunity, he then refused.
If I knew this, Dreamweaver, I had forgotten it. Thanks for the reminder. Who needs full immunity, or any immunity? Let's think: my best friend is missing after an evening that we've spent together. No one can find him/her. LE asks me to take a polygraph, presumably to eliminate me as a suspect in a missing person's case, or to verify that the details of my story are true as I know them to be. Either way, I am helping LE check me off their list so that they can concentrate on finding my friend. What do I do?
1. I say, "Wire me up! I love my friend! I would take any risk to find her!"
2. I say, "Not without immunity."
2a. I say, "Not without full immunity."
The missing piece here is that Clint has committed some crime for which he feels he needs immunity. He is willing to have people he knew think he is a p***-poor friend, a jackass who left his buddy without a ride and exposed him to some danger, or actually a murderer in order to avoid revealing--what?
The question is--what did he do?
And a corollary question: Let's assume for a minute that Clint was Brian's friend, that he cared about him at some level. How then do we explain why he wouldn't take a polygraph?
1. He knows that Brian is no longer alive so a poly can't help "save" him. (But he is not directly responsible for the disappearance or death.)
2. He knows that Brian is no longer alive (and he is involved in some way) so mystery is his friend.
3. The consequences he would face for helping the investigation with a polygraph are higher than the consequence of not finding Brian.
