"The Bidens" or Hunter Biden? If I'm not mistaken, Hunter is a grown man, an adult, capable in law of making his own decisions for himself, and without seeking his father's permission -- or even against his father's strongest advice and warning. And the evidence is clear that in fact, Joe Biden did caution his son, asking him, "are you sure you know what you're doing?"
How would you, as a father, force your own adult son not to do what you don't want him to? Take him to court (which court)? Tie him up in the basement? Shoot him?
