If you ever wonder if the law is different for some folks, I suggest you consider these two stories:
Former El Paso sheriff's deputy sentenced in fatal crash.
Man who stole military gear faces 12-18 months in prison.
Stop and think about that... while both events are deplorable, one of them was simply the theft of material goods that can be easily replaced. The other involved the (unintentional, but final nevertheless) taking of a life.
Doesn't seem proper. But I'm pretty simple-minded, so maybe I'm missing something.
