Alright, I've got several points to make:
1. The 'pit bull' is not a breed of dog. It's more a general physical description of a type of dog having a blocky head, short hair, and muscular appearance. I've seen everything from JRT mixes to mastiffs labeled as 'pit bulls' or 'pit mixes'.
2. The American Pit Bull Terrier was bred to fight other dogs and animals - never to fight human beings. In fact, when in the pit, the dogs were expected to be calm enough that the owners could actually touch the dogs and offer encouragement during the fight. When coupled with the breed's incredibly high pain tolerance, this capacity for docility around humans made the breed an unparalleled companion breed, if animal aggression was a non-issue.
3. The statistics for 'pit bull' bites include over a dozen different breeds as well as mixes that may show little or no resemblance to the APBT. Even when lumped together in such a manner, the statistics show that these breeds have a low number of bite incidents per number of dogs when compared to more common breeds.
4. The backyard-bred 'pits' sold as APBT's today are no longer bred for gameness, pain tolerance, or friendliness to humans as they were in old times. This is not to say the breed is completely ruined - only that it has fallen into the wrong hands and degenerated significantly as a general population. There are still good breeders out there, if you look.
5. Temperament testing shows the APBT to be on par with labs and goldens in terms of aggressiveness to humans. Again, a true gamebred APBT will score significantly better than this.
6. Anybody who feeds gunpowder to a dog is a moron - it does not improve the dogs' fighting ability whatsoever. Neither does raw meat; however, raw diets including meat, bone, and organs in proper proportion are ten times better for a dog than processed kibble (do you know what's in that crap?) and DO NOT make a dog mean. Search for 'prey model' or 'BARF' diet on google.
7. Dogfighting is not what it used to be. In a 'real' dogfight (i. e. old-fashioned fight by cajun rules), dogs rarely die, matches often go for an hour and a half or more, and the purpose of the match is to test not only fighting ability, but gameness - that is, perseverence even when clearly outmatched. The dogs are carefully matched and usually fight a dog weighing within 2 lbs of themselves. The dogs used in this type of match enjoy great diets, lots of exercise, and really enjoy the fighting. All the crap you hear about training the dogs by sicking them on poodles and collies, making them mean with kittens in bags as bait, feeding gunpowder, etc, do not apply to that type of fight. Today's 'street fighting' and ghetto dogfights are a joke - their purpose seems to be to offer the crowd the maiming or death of an animal as entertainment. I do not know the training methods or diets of dogs participating in such matches and do not care to.
8. Banning the APBT or similar breeds is stupid. If your argument is that they bite more than other breeds, then that is wrong, so you have no foot to stand on. If your argument is that their temperament is such that they are generally mean to humans, you are wrong and have no foot to stand on. If your argument is that they have the capability of killing people when they do attack, then I agree. However, so do most breeds. Dogs as small as Pekingese and Cockers have killed babies. Anything from 40-50 lbs on up has the capacity to kill an adult human under the right circumstances. So if you're going to ban a breed because it could kill a human, then you're going to have a long list of breeds to add.
9. Levying a $1k fee against owners of certain breeds is stupid, if the owner has done nothing wrong in the past. Maybe we should also pay an extra grand a year for our trucks since they're bigger than cars and can hurt people in accidents? Maybe we should levy a $1k fee against everyone who owns a gun, or a knife, or a ?
10. Here's my proposal - make new laws for dog ownership in general. Anyone that wants a dog needs to obtain a permit to buy one. Any breed that can grow above 50 lbs (or 40 or 30 or whatever limit you want to set) requires a special permit. As part of obtaining that permit, you must submit to a background check, you must show proof of insurance, and you must attend a training course with the dog. Same as with cc permits. It should also have to be renewed yearly in order to be most effective, IMO.
