(b) RELEVANCE THAT DEPENDS ON A FACT. When the relevance of evidence depends on whether a fact exists, proof must be introduced sufficient to support a finding that the fact does exist. The court may admit the proposed evidence on the condition that the proof be introduced later.
(c) CONDUCTING A HEARING SO THAT THE JURY CANNOT HEAR IT. The court must conduct any hearing on a preliminary question so that the jury cannot hear it if:
(2) a defendant in a criminal case is a witness and so requests; or
(3) justice so requires.
(e) EVIDENCE RELEVANT TO WEIGHT AND CREDIBILITY. This rule does not limit a party’s right to introduce before the jury evidence that is relevant to the weight or credibility of other evidence.
