I find it hard to believe that BC has not at least instructed the A's on the proper way to answer questions on the stand. That it is improper for a witness to question SA about relevance. Court is a serious matter and to be playing games does not reflect well on BC, I would imagine. The judge was very kind to GA yesterday but I imagine by the time of the actual trial that consideration will have worn thin.
Since GA is former LE he certainly knows better and almost appears as if he wants to be held in contempt. Generally people (jurors) expect more from a former police officer because they feel he does know better.
Example: My husband was a detective with a police department and my children were told by neighbors, etc. when they did something wrong that they should know better because "Your Dad's a cop." They still remember being singled out today. We just expect LE officers to act professionally and answer questions to the best of their ability. Does he not know he is NOT helping his daughter with such displays????
Another thing my husband always said, "Once a police officer, always a police officer." No matter how long they are out of the department people still expect them to act as if they are still connected.
