Court-Martial Trial Practice Blog
Federalevidence review has an excellent piece on leading questions during the prosecution direct. As part of the comment they say:
The Seventh Circuit recently explored the limitation on leading questions through FRE 611(c), admonishing the government about a trend that was disturbing, even if at most it would be only harmless error.
I see this regularly in courts-martials as well. There are times when it is proper to ask leading questions: general introductory matters, moving from a broad topic to another, developing the testimony or focussing a witness.
