How do criminal defense lawyers ask questions to defendants and witnesses

It takes a lot of skill to question the defendant's witness. First, ask questions about the core issues of the case, and don't ask irrelevant questions. Secondly, we should learn to ask questions about doubtful points in the case, especially those that are unfavorable to our clients. Finally, learn to split a question into multiple aspects to ask questions. Such a detailed question can maximize the discovery of unexposed doubts! Even change from passive to active.
