The purpose of adverse possession is when a neighbor's house accidentally gets built a foot onto the wrong property line, and nobody notices it until there's a squabble. Or there is an error on a deed, and Ma and Pa Kettle build a house and live there, only to be confronted years later with a competing claim due to error. The intent is certainly not to hand out free houses to people who know full well from the outset that they are trespassers. I suspect any judge would be absolutely loathe to award a squatter a free house under AP, and I suspect the rightful owner has an affirmative defense in the form of unclean hands. I also happen to agree with the attorney they interviewed on the telephone, regardless of any argument over an AP claim it doesn't mean they aren't trespassers in the meantime.
