If needed for training, there are some good examples of that precise method on the current TV show The Mentalist that can be clipped out. Of course its use is dramatized for television, with the main LE characters asking the basic initial interview questions then the title character pouncing in with the incriminating questions to observe reaction behavior. The true intent of the method is for the single interviewer.
