I've never been a Tony Stewart fan so I can't look at it without bias.
Tragic event that if both involved could have another chance at what happened, I believe both would do things differently. It's sad that can't happen. Now you either punish one side, or none.
I think what can be learned from the tragic event has been learned, and I don't think further discussion about it at this point is helpful or productive. That's just my opinion. I just don't really think I have anything more to add.
