I don't know that it does the world any good to lock a person up forever for making such a horrible mistake.
But it is a profound tragedy and I hope he uses whatever time and resources he has left to him to make amends.
Maybe by preventing him from killing any more innocent people? DUI is one thing. DUI at 156MPH shows a complete and utter disregard for the safety of those around him.
Forcing him into treatment and taking away his right to drive a vehicle might accomplish the same thing. Not to say that's all that should happen to him.
But putting a person in a cage for years and either never letting them out or only letting them out when they're old ... that's an enormous thing to do. I'm generally very skeptical of the societal value of locking people up, especially for extended periods of time.
It's satisfying from an emotional standpoint, but hard to justify in terms of the cost and when you look for actual tangible benefits.
The sad truth in the wake of a tragedy like this is that the person who died can no longer contribute anything positive to the world. It is still possible that Ruggs could. That's not an argument against punishment of any kind, but I do think it's important to push back against our cultural programming which tells us that people who make horrible tragic mistakes like this should be thrown away and forgotten about.
