Should large potentially dangerous dog breeds such as Pit Bulls and Presa Canarios require a license

Dog bite fatalities are extremely rare, accounting for about one in 167,000 deaths per year in the U.S. Dog bites represent 0.2 percent of emergency room visits. They are comparable in incidence to (but less severe than) accidents involving many common household objects, such as chairs. Attempts have been made to reduce this injury rate by banning breeds of dogs considered dangerous. However, follow-up studies show no impact on bite rates following breed-ban legislation.

The statement in your post is about scientific studies, and can't be applied to general, non-scientific, mis-informed media reports. IOW, while pit bulls ARE erroneously overrepresented in media reports, they ARE NOT in actual studies with actual evidence which prove that pit bulls aren't any more likely to bite than other breeds.

In the same document, the NCRC specifically addresses the problem of identifying the breed of a specific individual dog:

The best known study of fatal dog bites has attributed more fatalities to dogs identified as “pit bull type” dogs over the past two decades than to any single breed. News reports of dog attacks often identify the dog or dogs involved as pit bulls. This has led to a widely held perception that some breeds of dogs present a greater risk of injuring people than others and therefore should be eliminated from the population as a public safety risk, even though the researchers themselves caution strongly against such an approach. One of the co-authors of the study, veterinarian behaviorist Goleb, has stated, “It is frustrating for me personally because people who want to enact Breed Specific Legislation keep using the report to try and make a case against pit bulls. The whole point of our summary was to explain you can’t do that. (emphasis from source) Nevertheless, hundreds of municipalities have instituted statutes that prohibit or limit the ownership of pit bulls and occasionally other breeds, most commonly Rottweilers. Numerous objections have been made to this approach, based on lack of reliable evidence that pit bulls are overrepresented among injurious biters.

And the recommendations in the same paper specifically DO NOT advocate breed-bans, as you do:
