I know it sounds bad that he is not in prison, and it is in a way.
But his whole life is shit now, he is shit for the rest of his life. (that is if he chooses to stay in America)
He really should go back to the Taliban, who he obviously loves. It would be a better life for him.
Get himself an Arab wife to beat up, and abuse, and life is grand.
Maybe he could join up with ISIS, or Hamas, or Hezbollah...start killing gays, and Jews, and Christians.
He has lots of options, but living in America is not one of them.
