Cruelty to Animals is now a Federal Felony yet a Drunk Driver Killing Someone is Not

According to ABC News, animal cruelty is now a federal felony.We have no problem with this scenario whatsoever, except to ask that if animal cruelty warrants classification as a federal felony, why are people who drive drunk, drugged, distracted or plain dangerously, and kill someone as a result, not treated in the same ‘federal felony’ manner?

What is this if not an astonishing and frankly inexplicable imbalance of priorities?
