1. The first paragraph of my comments was meant in general. You don't have to feel the need to nitpick.
2. I have no idea how many crashes he has had. If he has 9 convictions for DUI only, I bet he has plenty of sober driving incidents as well in his life.
3. At 0.1, if it takes you overnight to sober up, you have health problems. That really isn't all that much, but I would agree that it probably represents threshold where driving ability starts falling off. At the very least, the ability to stay awake late at night starts falling off.
4. Regarding pilots, I would not want to ride in a bus with a driver who has been drinking. Those are commercial services and I can't really choose who the driver/pilot is so there better be standards above simply the ability to climb into the seat.
5. I didn't choose the murderer's sentence. The judge determined that based on his history as a pimp and drug dealer. It wasn't a death penalty case anyway. If he had a clean record, I think the lesser murder conviction would have netted a lesser sentence. That still has nothing to do with whether or not a LIFE sentence is appropriate for any DUI conviction. In Texas, a DUI is or can be low level felony so that is likely where it comes from.
On the other hand, I have also heard of people with multiple DUI convictions that get away with it with far less than this. There ought to at least be some consistency.
