One 'uh-oh' moment that left an impression on me is that the kids have been in town all week and Brad has not been allowed to see them because, according to Krista, "the court didn't order visitation with him." (This was when Krista was on the stand.) Krista made it very clear that she believes Brad should never see his kids again...not even if he's not charged for the crime (Sandlin pushed on this issue). Krista of course believes Brad will be in jail therefore his seeing the girls won't be an issue (the courtroom snickered loudly when she blurted that out), but it does show the level of hostility between the Listers and Cooper.
As for the webcam visits, the Listers allow the webcam visits to go longer than the allotted 15 min because the girls misbehave and are so rambunctious that it's hard to get a good quality 15 min in and get them to stay at the computer. Both Krista and Jim Lister said that the webcam visits are not working well because of the effect it's having on the kids. They recorded some of these visits and the judge will look at the recordings.
