Well, if the law allows her to ask for clemency after two years, you can bet she’ll ask for it. I mean, rationally, what’s the downside to asking?
Like it or not, the law has always treated taking a life with malice (and malice plus premeditation particularly) more seriously than taking one through negligence or carelessness. Actually, a DWI fatality is among the more severely punished of the “oops, I killed you” crimes.
As an example: a few years back in State College PA, a man killed a bicyclist while driving while legally blind. Around the same time, a man killed a pedestrian while driving drunk. The drunk got two years; the blind guy, house arrest.
Both of these crimes are “operating a vehicle with a known medical deficiency.” (The fact that one medical deficiency is voluntary is irrelevant, IMO.) I see no difference between the two acts, yet they are usually punished differently–lighter for the (typically elderly) driver with failing eyesight.
