They didn't go back and test all of Jones' previous samples, despite him popping for multiple substances, multiple times. They know that they lost our trust and respect for them after the laughable suspensions that Jones got, so now that TJ got caught red-handed, they are going throw the book at him. Same thing is Ruslan Magomedov, they want to act like they are hard on crime so we wont be as skeptical when they let someone off for "pulsing or a tainted supplement." TJ is guilty, but at least he admits it. Jones always acts like he is victim and that God loves him.
