I understand BD and CD frustration with not getting info from LE. I trust that they are keeping this investigation close to the vest and being very tight lipped to protect their evidence. Look how the story already changed about whereabouts since the cell pings were released.
I understand their frustration too. When Clint expressed his frustration with not getting info from LE, he was reluctant about it - desperate to help more. He didn't want to criticize he said. Billie, on the other hand, makes it seem like she's a victim of LE and is making it a contest, imo.
I don't think LE suspects Clint of anything; he goes where he pleases, no one is apparently keeping tabs on him.
I think Clint doesn't get as much info from LE as he'd like because the suspect is his ex wife's boyfriend. When Hailey first went missing, Clint's living across the field. LE is investigating Shawn and Billie. They can't tell Clint anything without expecting that he would naturally discuss it with Billie. If they were pursuing leads that traced back to SA (good bet), then there's a real danger Clint's gonna walk across the field and lose it on SA - getting himself in trouble.
Then, Clint moves away, he's still trying to work with Billie to get media, TES..,according to his interview tonight. Maybe LE could share a little more with him if they've ruled out Billie as a POI, but she announces that she is in frequent contact and friendly with the suspect again. LE still can't tell Clint anything without expecting him to discuss it with Billie, and LE still can't expect Billie not to tell Shawn (the suspect to whom she seems more compassionate than her missing child's father, imo).
Clint really can't win here. But, I agree with LE's position - they can't jeopardize their investigation.
