If you believe this you must also believe that they are involved in Noah's disappearance, otherwise why would it be so important for them to be on television. None of us (I hope) have ever been involved in something so horrendous so we don't know what we would do. I feel like a lot of what I'm reading is that the parents know something and the sooner they talk the sooner Noah will be found. IIRC, Jenise Wrights mother didn't go on tv to plead for her return and when the dad did talk everything he said was analysed to death. Some thought they were horrible parents and the dad had some accusations in the past so did he molest his daughter and kill her? When Jenise's body was found and a neighbor kid was arrested nobody went back and said , "sorry, my bad".
If we're frustrated without info, think what the family is going through. If they did have anything to do with Noah's disappearance I will be the first one to throw that stone but as it is now, they are victims.
JMO. MOO
