Did the Ramsey's not go back into the home because it might have been bugged?

After the police went through the home with a fine tooth comb, took video and gathered evidence, I wonder if the Ramsey's thought we can never speak in there privately because they probably bugged it? I don't think this is far fetched at all. In this era they did have good bugging systems that they could have planted.

Ramsey's stated they could not go back into the home based on what happened. I can believe that is part of it, but I believe that they felt it was no longer a safe place for them as it was infiltrated with many investigators who could have planted recording devices. I am fairly certain that it if they did hear them discuss things, it would not hold up in a court of law because it would have been an invasion of privacy being recorded without ones knowledge.
