Only way the players get banned and suspended is if they get caught lying after they been given the chance to say the truth without punishment. IE the buzzer thing with Altuve and other players denying it, if it comes out that is true it will differently be worst on them. Manfred made a mistake giving players immunity when the evidence was already there. I guess he did not believe or want to believe Fiers was telling the truth. Saying they get immunity for admitting cheating how does that make sense.
