Yes. But in this case (as in plenty of other non-mentioned cases), common knowledge and statistical facts appear to match up.
The problem, in my view, is that, like a lot of other debates involving dogs, there is a strong contingent of people who cannot be swayed by any kind of evidence whatsoever. Which makes for an irritating and boring discussion.
The general public can at any given time can normally identify only about five to ten breeds, the currently most common. But pit bulls are in fact one of those. Yes, there are mistaken ID’s but it is usually because those are rarer related breeds who are often ALSO unusually dangerous. They look similar because they were bred for similar purposes.
I have not read one post that is even slightly convincing to me that pit bulls are not A.) a breed and B.) an unusually dangerous one. And like I say, I have no belief system to defend here.
As far as breed-specific laws, I have no opinion. Cutting down on the popularity of the more dangerous breeds is probably a good thing, if it can be accomplished. Note that they are not more dangerous because they bite more. My guess is that this type of dog bites less than more highstrung breeds. They just do a lot more damage when they bite, because they are selected to do a lot of damage when they bite.
