Biden has always been a piece of shit. That said, he's old, his other son is dead, and his loser son got caught up in a shitstorm that had less to do with justice and everything to do with politics and optics. The country decided that it is happy to go down the a fully corrupt, inept and fascist rabbit hole, and Biden opted to save his loser son and tell everyone to go fuck themselves and go suck an mushroom shaped cock.

EDIT: Don't get mad at an old man for choosing to save his son. Be mad at a system that allows a man to abuse his power to protect his friends and family from consequences. For once, a proper use of "Don't hate the player, hate the game".
