December:
Constitutions, both state and federal, describe law - the highest law in the state, and the supreme law of the land. But they are not useful tools in ascertaining facts in dispute. The jurors did not have to determine what the state or federal constitution said – they had to determine what events happened. The judge is the one that determines how those facts apply to the law.
Arguments must derive from the evidence presented. A lawyer argues to the jury that, based on the evidence they have heard, they should draw certain inferences as to what actually happened, or they should believe one witness and disbelieve another. A lawyer does not need to ask the jury to apply the Constitution to a case, because that has nothing to do with the facts of the case.
A lawyer should - and is - always free to argue to the judge that the Constitution creates law, and should be interpreted in a particular way. But making such arguments to the jury is confusing, and improper.
We have a long list of restrictions on what a jury may hear. For example, we generally do not permit an accused’s prior criminal convictions to be heard by a jury. Why? Because they are generally not relevant to prove he commited the act under consideration. The knowledge may prejudice the jury into convicting him because he’s a bad guy, as opposed to their finding the elements of the crime proven.
In fact, the jury cannot hear any evidence unless it’s relevant. Relevant evidence is that which tends to prove or disprove any fact under consideration. Even if evidence is otherwise relevant, it must be more probative than prejudicial – that is, if it has only slight value in proving a fact, but highly prejudicial value, it will be excluded.
The contents of the federal or state constitutions do not lend themselves to proving or disproving any fact under consideration. It was proper for the judge to bar them.
By the way, I am a supporter of the right to keep and bear arms, and a lifetime NRA member - to the extent you may question my pre-existing bias on this particular case’s issues.
