And yet, earlier today, the vikings reinstated peterson, punting on any further discipline while the case is pending. We must defer to the legal system to determine whether he went too far. But we cannot make that judgment. Reporter and peterson himself added a note of remorse. I know that many people disagree with the way i disciplined my child. I also understand after meeting with a psychologist that there are other alternative ways of disciplining a child that are more appropriate. Peterson could face up to two years in jail for what happened. But its not up to the court of public opinion. Eventually, the jury of 12 peers will decide the proper punishment.
