Black Friday, 2011. While $11.4 billion was being spent at retail stores and malls, some over-enthusiastic customers decided to make things even more interesting:

• At a Walmart store in Porter Ranch, California, a woman fired pepper spray into a crowd in an attempt to clear a path to an Xbox. 20 people were treated for injuries.

• Gunshots were fired in a parking lot outside a mall in North Carolina around 2 am. While no one was injured, many shoppers were sent into a panic.

• Believing he was stealing a video game, security guards at a Walmart in Arizona left a 54-year old grandfather bleeding heavily from his nose after slamming him into the ground. The grandfather claimed he put the game in his pants to keep it safe while trying to protect his grandson from getting trampled.

• A shopper was shot outside a Walmart in San Leandro, California at 1:45 am after members of his family resisted two armed robbers attempting to steal their purses. The wounded man was in critical but stable condition.

• After punching another shopper while waiting in line to buy video games, a man was stun-gunned by Police in order to subdue him.

• At 1:15 am, customers waiting in line outside a Hollister store in SOHO were a bit upset after learning that that particular location was not opening until the next day. They got tired of waiting for the door to open and broke it down instead, looting the store in the process.
