Let's say a witness is called to the stand. One who has been prepped by whichever attorney called them. When asked if they swear to tell the truth they ask for a lawyer. What happens next?
I know there are legal reasons that can excuse one from needing to testify1 and consequences for refusing without good reason. All seem to be legal reasons that a hesitant witness might realize need to be explained by someone qualified in law that has the interests of the witness at heart. If the witness believes no one else in the courtroom is primarily obligated to protect them can they insist on their own lawyer?
