Because only in America are people ready to kill each other for things they don't need and can't afford, after spending the day before being "grateful" for things they already have.

Black Friday got off to a rowdy start at a San Antonio mall where police say one shopper pulled a gun on another who punched him in the face while they were waiting in line at a Sears store.
Police Sgt. Rob Carey tells the San Antonio Express-News a man rushed into the store when it opened Thursday night to get to the front of a line, started arguing with people and tried cutting in front of them.
One man who got punched pulled a gun and that scattered shoppers, including the impatient line-cutter who took cover behind a refrigerator. Then he fled.
Carey says the man with the gun had a permit to carry the weapon and isn't being charged with a crime.
