Of course I disapprove of these kinds of videos. At the same time, I wanted to know what lawyer and what defendant had the "you know whats" to try and challenge that kind of law. I came across
THIS article that seemed to explain why the law was shot down, and after reading it, I have to agree with the Supreme Court on this.
The cliff notes version of it is the defendent challenging it was claiming to use a pit bull fighting clip from Japan as education to distinguish pit bulls trained to fight or to hunt. It was not an animal crush proponent bringing the challenge, thankfully. The supreme court says that the law was too broad and could effectively ban legal media such as educational and hunting videos and magazines, which violates free speech rights. They were not trying to say animal crush videos are ok to have, but that the law has to be more clearly defined so it doesn't affect legitimate media.
Hopefully that clears up some of the hysteria that I'm sure is going to surround this issue, and I'd love to see a better law put in place myself.
