Too many people on here are incapable of reading an article or reading comprehension. Here is a DIRECT QUOTE from the article:

Paula Whitley, Tuscaloosa chief deputy district attorney, told AL.com on Tuesday that "there's nothing we could charge [Miller] with."

Now, explain what different ways you are aware of that he could/would be charged with a crime, that the Chief Deputy District Attorney for this region is not aware of and that had not been considered for which evidence is available and that a conviction would be probable.

I’ll wait.

He is projected to be a top five pick. This changes nothing. He didn’t do anything wrong. He didn’t commit a crime. If the state of Alabama could charge him with a crime, they absolutely would. You can legally carry and possess a firearm in Alabama without a permit or background check. He transported a gun that was owned by an individual directly to that owner.
