A) Yes. If JM wants to ask for the judge's help, he could probably get an instruction to answer the questions. BUT he needs to ask when the question he has posed is not flawed in any way, and when her answer is just really obstructionist. Most of the time, it seems like either he's asked a not-too-great question or she's making a tiny but not completely improper distinction. For example, when JM said "OK, you arrived there when the sun was setting," and she argued that she hadn't said the sun was setting, that was true. She hadn't said that. And perhaps it was a silly thing to argue about, but since JM was making a big deal about the time of day, the judge can't tell JA to ignore any little mistakes he might make.
B) No haha.
