Sounds like the next ballot action should be any elected official who offers up legislation to repeal a ballot initiative immediately loses their seat without any further action needed. If enacted by a ballot only a ballot should be able to repeal it and anyone who suggests otherwise doesn’t belong in office.

Every person who kills a billionaire does so in self defense.

It is a piece of evidence. The jury would decide how much weight to put on that evidence. Depending on other factors, the jury could decide it is compelling and provides reasonable doubt, or, they could decide it is not compelling and disregard it and look at all the other evidence regardless of this particular bit.

Edit to add: Prior to trial there is a jury of one, the prosecutor. There is a chance that the prosecutor will find that evidence compelling and not even bring charges, or dismiss them if they were already brought.

They should be feeling like shit. They are acting like shit and following unconstitutional orders. Grow a goddamn spine and frag any officers who give you unconstitutional orders.
