This should fall under prosecutorial discretion. Prosecutor should refuse to prosecute, the young lady should then be given her gun and ammo back and then she should receive a state trooper escort back to the border.
When we get the presidency back, I’d like to see the fed government start requiring states track how many people are convicted ONLY for gun control offenses. Cases like this lady. They could do this by attaching it to any one of the many govt dollar hand outs they give to the police departments.
That would start making the case that gun control laws do nothing but make criminals out of honest people.
