Sure, lets look at those one-by-one:
The "American Bar Association" is not a valid source about dog behavior. They're lawyers being paid to push whatever agenda gives them the most money. Not gonna comment on that one since its missing any other scientific evidence.
The 2014 American Veterinary Medical Association "literature review" is being picked and chosen from in the Wikipedia article. Quotes from the very same report that were conveniently missing from the Wikipedia article:
"While small dogs may be more aggressive their size means they are less likely to inflict serious bite injury except on vulnerable individuals"
"Certain large breeds are notably under-represented in bite statistics such as large hounds and retrievers (e.g., Labrador Retrievers and Golden Retrievers)"
"...cases that resulted in very severe injuries or fatalities, pit bull-type dogs are more frequently identified..."
The 2013 Canadian study isn't being cited in the Wikipedia article. Instead, the citation is a link to an opinion piece that mentions the said study without giving any references to it (no links or even author or institution name). As far as I am concerned, that Canadian study is made up, unless you can find it and we discuss it. I never saw any respected author mention a scientific study and then fail to completely give any references to it, not even freshmen in university would do that.
On the other hand, this is an actual cited quote from that opinion piece that's directly linked in place of the Canadian study:
"Breed-specific laws strengthen existing dangerous dog laws by targeting some of those prime offenders."
The Dutch ban on dangerous dogs which was lifted on 2008, was more or less re-instated in 2017. Wikipedia conveniently forgot to mention that:

Using one law that in your opinion isn't sound, as an argument against laws in general having no merit doesn't make a lot of sense either.
A law isn't a scientific proof, but at a minimum it tells a lot that a problem in society has become so prevalent to justify passing said law.
If the number of victims and complaints were so negligible, the law wouldn't have had enough momentum to pass the all of the bureaucratic barriers, including the European animal rights groups, who are far more fierce than the US ones.
