I was only able the watch the last half of Animal Witness... but I really enjoyed that half. I love Badrap, and I've had the opportunity to meet some of the founders, and they are who I would go to if/when I adopt a Pittie. I thought it was VERY moving.
It was pretty shocking to hear that most of the dogs were not DA; but I highly doubt that Badrap would lie about any of them. They do have a plethora of information, about DA, on their website. I'm sure the special could have been handled much, much better (if Mia was the producer : D) but honestly, it's a breath of fresh air, to me. It is not perfect by any means, but angelizing Pit Bulls is a whole lot better than villainizing them... at least it's a step in the right direction. And, for all we know, Badrap could have provided plenty of insight about DA and handling Pit Bulls, but it might have been cut out. After all, it was only an hour show, and I think the goal was more to stir emotions than anything.
