I take it Louisana doesn't allow jury nulifcation?
Dagnabit! I did do a spell check...
What, are you talking about judgment non obstante veredicto? Yeah, we have that. But the standard is pretty high. It's hard to pull off, and likely to be overturned on appeal. Especially if used against a criminal defendant.
All a jury can do is acquit a particular person accused of breaking a law. Even in places where jury nulification was common and accepted, that was true.
One thing that has changed over time, however, is that the amount of harm an indictment can do. It used to be that an innocent person who was indicted could expect to be acquitted within a month and there'd be little point indicting people if their cases wouldn't hold up. Now, the government can seek to punish people administratively before trial, and just shrug when the people are finally acquitted.
