1. This "steeple" is defined as "attaching the ends of your fingers" in a workbook, but I can't find it in a dictionary. Is it correct?
2. Are these "prosecutor" and "attorney" different people of the same person? Considering the context, "attorney" seems to be a mistake as the attorney is for the accused, while the prosecutor is against the accused.
ex)..Interestingly, when a prosecutor steeples as his witness testifies, the value of the testimony is enhanced because of the attorney is perceived as being confident of the witness's statements...
Is this text by a native speaker? It is unclear to me and has basic errors in it (because of)- it looks like an intermediate learner's writing, where the level of language struggles to match the ideas in their head- the last part in particular. I haven't come across the term, and the definition doesn't make much sense- attaching them to what? I guess, it means pushing your hands together so that they look a bit like a steeple.
