I see the defence as asking good questions that are intended to clarify. For example, police testified that they used a tool that detects blood and found blood on light switches. The defence clarified that it is a 'presumptive' test that means nothing without additional testing. The defence also questioned Jennifer on her statement to police after discovering the scene - she did not actually say that someone came to the house, killed her family, and took the bodies. At this time, the defence goal seems to be to keep the prosecution, and their witnesses, honest.
