In reply to the discussion: Poll question -- You're serving as a juror... [View all]What you are describing is distinct from what you are trying to ascribe it to.
Defense attorneys can ask a judge to dismiss a case, due to lack of evidence. In fact, they can do so in a pre-trial motion, or in a motion to dismiss after the prosecution presents its case.
But it could never happen by way of the jury hearing the defense present its witness(es).
Our system of justice is flawed, and has very real problems. Yet adding fantasy situations that can never happen does not present any meaningful options for discussing them, or any of the other fantasy issues applied to the OP.
Also, it is true thaqt prosecutors have the burden of proving their case ..... one votes either "guilty" or "not guilty." But, as everty judge instructs every jury in a criminal case that goes to a jury trial, they should wait to hear all of the evidence before reaching a conclusion. To assume that only involves weighing the prosecutor's case would be to fail in one's solemn duty, for good defense attorneys frequently raise "reasonable doubt" (even where the accused may well be "guilty," but the prosecutor simply has proven it beyond a reasonable doubt) ..... and even a somewhat-talented defense attorney can do so with a client who is actually innocent of the charges.
It's probably better if we stick to what actually can happen in a criminal case.
