With all due respect, while I understand the need for information, there are other small children in the home. I don't blame them one bit for trying to put up some type of protective barrier in place. If they are innocent, I am sure they want their baby back and are following the advise of people more experienced with media relations than they are. It sounds to me like they are realizing that the media is more interested in salacious stories and cornering the parents rather than finding the child.
National media will be far more capable of getting the story out, IMO.
It is a tough call, but I don't see how harrassment will do any good in finding the child. If they are guilty, harrassment won't help. Good detective work on the part of LE will. As a community, we need to allow them to do their jobs, cover the story and get the word out that Lisa is missing.
This is all JMO
