There will be no pardon, because Joe Biden says so. He never lies.
Personally, I think it was right to indict Hunter, since other people have been indicted for this, but I would be happy if they just fined him $5000 and told him to knock it off. I guarantee you, there are alcoholics and weed smokers on this forum who have lied on Form 4473, other gun owners know about it, and they haven't turned any of them in. I don't think Biden was going to run around jacking people with a .25 automatic to get his next hit of crack.
I don't believe the prohibition on addicts and illegal drug users was intended to net people like Biden, Drew Barrymore, Robert Downey Jr., Chevy Chase, Kitty Dukakis, or Betty Ford. It seems like a clumsy tool that destroys people's civil rights indiscriminately.
Based on Googling, I think he will get a little prison time if his appeal fails. His real problems will come after his other trials, and then if the influence-peddling thing blows open, God help him.
Form 4473 asks applicants to list their weight. I always guess. Should I turn myself in?
