No. Manslaughter, yes. Criminal negligence yes. Genuine murder, no.
Dogs are not the same as guns. If one can be negligent with guns, one sure as heck can be with a being that moves on its own and has a mind of its own.
I could do this for hours. In some ways guns are much safer than Pit Bulls because they are easier to secure, easier to confine to a property, can be disabled from doing any harm to anyone with locks, and a gun will never make a decision, all by itself to do harm to any person. A gun will never spend one second of time with a pack mentality when there are several other guns present, and a gun will never take a single step going anywhere under its own power.
When you make the choice to own a dog that is more prone than any other dog breed to attack people randomly causing great bodily harm and or death, you must assume full responsibility for your choice, and their actions. You have made the choice that puts others at risk.
From the point of ownership forward if your dog kills someone it is homicide. If you intentionally let or have them kill someone it should be murder one or two.
If for what ever reason they escape and kill someone it should be negligent homicide.
The penalties for death by pit bull should be exactly like you or someone else using one of your guns to kill someone.
