Justice Served?

Michael Vick is out of prison now and I'm still disgusted. I'm not upset about him going because I believe one should for such a crime. Still I've never known anyone that went to jail, let alone spend any serious time in it, for dog fighting. The fact the people spent so much time crucifying him seems like such an absurd waste of time. Drunk drivers, rapists, domestic abusers, etc., can get off with the same amount of time or less. This is not a human versus animal, who's more important debate. I'm just saying that too often, dangerous repeat offenders can very easily spend only a couple of days or months in jail and be back out in society. If we all spent as much time on updating laws and justice systems as was spent on Michael Vick and his crime, imagine how much safer would humans and animals alike be.
