Ok, I only link to Kotaku if the story is REALLY good because I tend to not like them but I got to this link through gamekyo:
Electronic Arts today contacted game writers around the country asking them to return the brass knuckles they were sent as part of a promotion for Godfather II. The representative that contacted me said that the company wanted to make sure that the brass knuckles were "properly disposed of." He declined to comment any further. Contacted by email Friday, an Electronic Arts spokesperson verified that the company is asking that all of the brass knuckles shipped out be returned.
Brass knuckles or metallic knuckles are illegal in many of the states that they were shipped to. They're also illegal in California, where EA is based.
In Colorado, possessing an illegal weapon is a class 1 misdemeanor, according to a Denver police spokeswoman. Illegal weapons are defined as a blackjack, gas gun, metallic knuckles, gravity knife, or switchblade knife.
Electronic Arts did not respond to emails seeking comment about the legality of the items they shipped and whether they faced any legal actions for shipping them across state lines.
Also, shipping them to or from Califiornia (where EA is located) is also illegal with this as a punishment:
The law is punishable by a imprisonment in a county jail not exceeding one year or in state prison.
