Just another nuisance brought into the US by the invaders. Correct me if my understanding is wrong, but I think cockfighting is more likely to be a "south of the border" thing now imported to perhaps a neighbhorhood near you!

Nine Arrested For Cockfight

(Ogden, UT) -- Nine people have been arrested and nearly 100 chickens confiscated as police busted a suspected cockfighting ring in Ogden on Saturday. Responding to an anonymous tip, police discovered a cockfight in progress at a home in the 200 block of Peterson Street. The Humane Society of Utah believes cockfights happen across the state almost every weekend. Investigators say this operation was pretty well protected. There were tall fences surrounding the backyard, where the fights took place, and the house was also set apart from others on the block. Police seized vitamins, syringes and leg razors, which are used as weapons in the cockfights. The nine people arrested face counts for fraud, animal cruelty and tampering with evidence.
