These are two completely different points, and Denny has nothing to do w. Burden of proof. The burden of proof lies only with the State, and all they have to do is prove the elements of the charges beyond a reasonable doubt. The defense is required to prove NOTHING. It is their right to rest their case after presenting no witnesses. They are not required to present opening or closing. Madeleine is correct that motive need not be proven (although IMO it is wise for the State to give something, even if it's just argument in the closing)
Denny deals with the defense being able to name alternate suspects by name in open court. The defense is absolutely able to argue "Someone other than LE or Steven Avery killed Teresa, and the tunnel vision of the investigation is what protected that person, Teresa's real killer" (which they did argue) but if they want to say, for example: "Bobby Dassey killed Teresa, and the tunnel vision of the investigation is what protected him" then they need to provide the Court with evidence in order to use his name. I agree with the reasoning behind Denny- Bobby Dassey is NOT on trial, and the defense shouldn't get to point the finger at anyone they want. However, I think Denny's three prong test places too much burden on the Defense- IMO, opportunity and access to crime scene should be sufficient, because, in the hypothetical above, all the Defense is asking for is to use Bobby's name- which could hurt his reputation, but ultimately, he isn't the one on trial, he won't be imprisoned for what the Defense says, so the burden could slightly lower, JMO.
