Why not look at why the existing legislation is inadequate - because it doesn't address this breed... ergo it's been updated to correct that.
Because it wasn't properly enforced.
Again this is not monocausal! It was banned, then ruled to not be a pitbull then... *the problem*... now.... legislation updated to fix the problem. Your previous vague narrative is backwards.
The legislation states that it is illegal to breed from a Pit Bull.
American Bullys include Pit Bull in their bloodlines.
So it doesn't even have to
be a Pit Bull, just bred from one, to be illegal.
The cause of the problem is breeders furnishing the demand for status dogs with improperly bred examples, and selling them to owners who will not treat them properly.
Also re "the cause" that some owners are total idiots doesn't negate the fact that this breed exists and is inherently dangerous in the hands of *any* ordinary owner.
That this dog, as with many other breeds, may require a certain level of competence, and is thus not suitable for the likes of first time owners or a particular type of person, does not make the breed inherently dangerous.
Banning it does tackle that bad owner aspect too as you can no longer legally breed or import them, the "total idiots" can also be refused a certificate of exemption. The issue you're bringing up is dealt with in the legislation you're critical of.
It wasn't "dealt with" when Pit Bulls were banned, as they're still being bred and imported.
It wasn't "dealt with" when Pit Bulls were being bred from to result in American Bullys.
Bad breeders and owners have been causing problems long before the legislation and have continued to do so since, arguably getting even worse.
Legislation did
nothing to stop these things from happening, and more/amended legislation is equally ineffective. The only way the government could do
any less about this is if they just "strongly condemn" these events.
