Pitbulls are banned here in the UK but people who do illegal dog fighting still breed these dogs.

It all came to light recently when a dog belonging to a drug dealer mauled his neice to death at home. In the papers, they never state what happened prior to the attack, they just tell everyone how the dog mauled the child to death and people think the dog just decided to get up and go maul the kid for no reason.
It turned out that the dog was pitbull and it was destroyed in the back yard. After this episode, they found a whole load more pitbulls being bred for dog fighting and they took them away, apparently connected to the original guy in some way although he didn't do dog fighting himself, he knew the breeder of the pitbulls found. There was footage of an officer carrying one dog out to the van and its tail was going ten to the dozen, bless the poor thing.

No doubt all of these dogs would have been destroyed for being pitbulls.

It's such a shame that it's often the idiots that are attracted to this type of dog. It isn't the dogs that are dangerous, it is the idiots that too often own them as status symbols.
