Why can't we be friends?  Why must violence dominate what is supposed to be a festive, happy-go-lucky time of gaming? Two gunmen, believed to be in their teens, approached a line of 15-20 people outside a Putnam, Conn. Wal-Mart at 3 a.m. and demanded money.  Michael Penkala, a Massachusetts man who traveled all the way to Connecticut to buy a PS3, refused to hand any money over and was shot in the shoulder and chest. Penkala was transported to the University of Massachusetts Medical Center, where he is in stable condition.
