Should Dogs that attack people be destroyed?

I know there are a lot of owners out there who would State "The dog would not hurt a fly" typical mom saying their children are not bullies. When a dog attacks a human with no provocation do you believe it should be destroyed?

Do you think the dogs owners have a lot to do with the dog aggressive behaviour?

What would you do if you had a gun and a dog was in the process of mauling your childs face off?
