One the one hand I can argue that I think the appeals court erred. The law merely states that anyone in posession of a weapon with an altered or obliterated serial # is presumed to be the one who altered the #. The presumption is rebuttable by the accused during his trial. How this refutes the presumption of innocence is unclear since the presumption of wrongdoing is rebuttable and the accused has his day in court. The presumption is merely the tool which allows the DA to charge the party with the altered gun.
OTOH, I can also argue that the court was correct in it's ruling. The law expressly states that posession of a weapon with an altered/obliterated serial number is prima facia evidence of guilt on the part of the posessor of the weapon. That sort of does away with the whole concept of a trial to determine guilt if the law states that one is guilty because the law says so.
Thus, I guess the newsreporter wasn't so clear in his reporting of the appeals court decision if both sides of the argument can be logically argued.
