Whatever, you guys are flat out wrong. If he would have killed someone while driving drunk, then yes, give that much time. But for just being drunk, wtf. Some people can drive perfectly fine while drunk. You're just assuming he's going to hit someone while drunk and punishing him as if he already had.
I don't even drink, I can't stand alcohol, but as a libertarian, it's against my beliefs to punish someone for what you "think" is going to happen, rather than what factually happened.
The fact that you guys think he deserves a life sentence for driving while intoxicated scares me alot more than him actually being on the road intoxicated.
