Surprise surprise a staffie.. While any dog can snap or bite, you never hear of labradoodles running amok/savaging people - or basset hounds or cocker spaniels....
It is nearly always pit bull types.
Are these incidents down to the breed or the owner or a bit of both? 
Personally I think it's the latter. So often (present company excepting!) it seems to be the most unsuitable people who are attracted to these breeds - which however need careful management. A former neighbour was a prime example. His staff was never even walked. It got a few yards into the garden that's all and it was an accident waiting to happen. But the unfortunate dog would have paid the price if it had lost it.”
Careful Mrs G, if you say this on some sites they'd be on you like a pack of hounds

. It's true any dog can bite, but, not every dog can inflict the same amount of damage. A pug or shih-tzu isn't going to do half as much damage as a powerfully built dog with an equally powerful jaw is it? Not to mention the fact you would have a chance of shaking or kicking the former off but the latter - forget it. It's always the same breeds that crop up in these incidents, terriers, which were bred for one reason and one reason only - to kill. It is in their nature to attack other things and tear them to pieces, they weren't designed to be cuddly easy going family pets, they were designed to go after various other animals and kill them, straight to the job with no messing about.
Apart from the the odd exception they aren't an easy going mellow breed, their wilful, highly strung and aren't afraid to hold back. Of all the breeds I've worked on, the terriers are the only ones to have a serious attitude problem and snap without warning. Putting a dog with this type of temperament and nature in the hands of someone who doesn't bother to train it properly, or trains it the wrong things is asking for trouble and it's usually somebody else who pays the price. These people go after certain breeds because they look tough and menacing, many will shoot you down in flames for saying that but it's true, they do, why else would they want them? They wouldn't want them if they were cute and fluffy would they? What is going to intimidate you more - a gang of youths with a pekingese or a gang of youths with a bull terrier? So to answer your question, it's a bit of both, breed and owner. It is not just down to the owner, while how a dog is kept is a huge factor, the nature, genetics and breed traits also play a part.
