I think this is one of the many reasons that we should get rid of this ban. Unless you can prove the dog is dangerous, I really think what it looks like, is a bad reason to ban a dog. Pitbulls are dogs like all dogs and not inherently evil, like some ignorant people think.
Denver Animal Shelter does a great job caring for the pitbulls that do end up in the shelter and work with rescues and other shelters outside of Denver to transfer those dogs, not kill them, like this article describes. Things in the distant past were probably much worse, but as of today in 2014, DAS does good work and anyone that believes otherwise should visit the shelter and see how nice it is and how well the staff and volunteers take care of the animals in it's care. I think it is in bad taste to post this picture that someone took, supposedly, it paints an unfair picture of the shelter today in 2014.
