Can an attorney refer to testimony made in preliminary hearings during their opening or closing arguments?
For example, let's imagine that in a preliminary hearing before the trial has started, a cop testifies and during that testimony describes the defendant as "crazy". Can the attorney for the defense then re-iterate that in the opening argument, saying "patrolman so-and-so even called my client 'crazy'... etc".
Taking this one step further, can an attorney show portions of the transcript from a preliminary hearing to the jury? For example, let's say that a witness gives testimony during the trial that contradicts what the same witness said during a preliminary hearing. Can the attorney show the transcript of the prior testimony to demonstrate that to the jury?
