Re: Reasonable Doubt
When such a situation arises, the judge will halt the trial, send out the jury, and give advice (e.g. a bollocking) to the defense counsel. Upon resumption of the trial, the jury will be instructed that for legal reasons it should disregard the last question and any implications it might have raised, and the defense counsel will apologise for his inexperience by asking such a question and move onto another topic.
