In 1998, Puerto Rico passed legislation that banned "pit bulls" and "Pit bull mixes" from the island. Earlier this week, they made a major step in repealing the 1998 ban when their legislature passed a bill to repeal this ban. (this article was run through Google Translate, so it's a little rough to read). The bill now just waits final signature from Governor Luis Fortuno.
The removal of the ban was strongly supported by the College of Veterninarians in Puerto Rico as well as the Pit Bull Association of Puerto Rico.
It is estimated 50,00 'pit bulls' currently live in Puerto Rico -- and because of the ban, more than 3,000 were killed in the past 2 years alone.
As people learn more and more about 'pit bulls' and the ineffectiveness of the laws that target them, more and more places are deciding to repeal their bans in favor of more effective (and rational) dangerous dog legislation that targets the dog based on its behavior, not "breed".
Here's a second article, with the same, yet somewhat contradictory numbers (including some different population numbers, which should have translated well).
Congrats to the people and veterinarians in Puerto Rico.
Hat Tip to Jodi at Bless the Bullies on this, which is where I saw the news first.
