So I'm a day or two late on this, but with New Mexico banning cock fighting, Louisiana is now the only state in the Union to allow cock fighting. Lovely. I was sent a few good articles on the subject, and I'll list them here.
A truly sad quote from the article:
"This has been one of our dirty secrets for a long time, and quite frankly, this [ban] has been a long time coming," said Democratic State Rep. Peter Wirth. "I'm thrilled that we're finally putting Louisiana in the rear-view mirror on this issue."
A good editorial on the subject, and gives you a bit of background on why it has been hard to ban it here.
