What causes people to kick, shove and even stab each other on Black Friday?
Each year there are reports of violence during the Black Friday sales. Last year, in Philadelphia – the City of Brotherly Love, no less – two families fought until one of the women ended matters with a stun gun. In a New Jersey Walmart, a belligerent shopper had to be pepper sprayed by police. And in Virginia, one man slashed another with a knife in an argument over a parking spot. This year, there are sure to be similar cases.
