I assume you are in the "Pit Bulls are just another dog" group? - or are you referring to something else?
Let me get this straight - you are suggesting that this article had something to do with preexisting municipal bans? And if you plan to pont out that "no, I said emotion did" don't bother; the stats are emotionless. You may not like the result, but the point is valid so let's not discuss the merits of pitbulls - that horse is a grease spot anyway.
A more useful direction based on this data may be: if a disproportionatly high number of low-lifes own a particular breed, their lack of proper care and attention could be contributing to a disproportionatly high number of attacks by that breed.
What?! It's the owners that are the problem, not the dogs?! Hey that's where you wanted to go, but it was a much shorter trip using the stats, eh?
