The parents DID talk to the media several times....It is my VERY strong opinion that LE has told them NOT to. Same goes with the store clerk.
LE is working in the background and we know but a smidgen of what they know/have. I, for one, will let them do their JOBS by not interfering with potential witnesses or questioning why certain people aren't talking to the media.
This isn't about US, this is about a defenseless baby, who is most likely dead, and LE will do anything to find out what happened to him.
What other interviews besides this one?
When I search for interviews with the parents, that's the only one that comes up.
