A lawyer puts up an expert witness to testify on a technical matter. The opposition leads him through several questions on "cross," and then concludes with, "So it is possible that X could have occurred?" (X being an event that helps the cross examiner's case.) The witness says "yes," and means to say "but that is not likely" when the cross examiner cuts him off.
Can the first lawyer then "redirect" with questions like, "So you say X is possible? How likely do you think this is? Why do you think this is unlikely?" etc.
Under what circumstances "can" this be done? ("Can" in this context has two possible meanings. 1) is "legally admissible or allowable. 2) is legally "advisable.)
