Anyone who kills someone else while driving should be charged with manslaughter.
Not necessarily. Some accidents are simply not avoidable. And some people are just naturally not as skilled as others. That is a risk I take into account every time I get on the road. (The road built with my tax dollars, by they way.)

They should still be charged. If it is found to be the person's fault then they should be convicted.
It's tempting to argue this from the 'limited government red tape' perspective, but...
I'm sure if I killed someone for any reason I'd feel terrible about it. The details of many, if not most, fatal accidents are probably pretty clear and it would ordinarily be just fine to clean up the mess without undue hardship, but...
I will bet that there are more than a few cases where the participant(s) are known to the authorities and are let off the hook due to their social rank or for good-old-boy reasons. I would not be adverse to enforcing a formalized no-exception process for clearing anyone of manslaughter no matter what the circumstances.
