The 5th Amendment to the U.S. Constitution guarantees you the right to remain silent even at trial regardless of the nature of the charges. A Utah defendant can never be forced to give a testimony against them self in a possession of child porn case and may remain silent at trial but are free to testify if they wish. A defendant is a competent witness on his or her own behalf and such testimony should be given the same consideration as any other witness. The fact that the defendant stands accused of a crime is no reason to reject his or her testimony. In fact, in many cases only the defendant can assert a particular defense. If the defendant is relying upon an entrapment, mistake of fact or alibi then often the defendant’s testimony is necessary.
