More often than not, the defendant in a criminal trial is advised by his attorney not to take the witness stand because the defendant would have to face cross-examination by the prosecutors.
But lets assume the defendant decides to testify. He is asked favorable questions by his defense attorney and makes a good impressions upon the jury. Next up would be the cross-examination.
What happens if the defendant from this point on remains silent and refuses to answer any further questions, first and foremost by the prosecution?
What would be the legal ramifications? The defendant still has his 5th amendment rights, or does he?
How will the trial proceed?
