IMO, if you decline to cooperate with what LE asks you should be able to expect that they may be a little less cooperative with you.
LE have the legal right not to share any information about the investigation with anyone, let alone parents who don't want to answer questions.
FWIW, I don't believe LE are going to share much info with the aunt and uncle either. They may have some questions for them.
Agreed
I think we all know that just because LE doesn't announce publicly that they're naming an official suspect, doesn't mean they're not considered a potential suspect, or that LE isn't focused on them. We just have to read the threads about jersey, the male neighbor or anyone who isn't the parents to know that.
If this story is even true, we don't know if this is just more spin and selective phrasing by their defense team meant to trash LE. But even if it is, if LE can't clear the parents, they don't owe them anything, may be harsh but LE's obligation is only to Lisa not them, their job is finding Lisa, not coddling parents who refuse to cooperate. The parents made their choice, they exercised their rights to not cooperate. LE has the right to keep anyone in their focus as a potential suspect until they can clear them.
Besides, weren't we told that DB/JI have turned to the FBI to find their baby, that they're fully cooperating with the FBI? So surely the FBI would be keeping them in the loop, if they have such a great relationship with them.
