MAVERICKS OWNER MARK CUBAN said today that the Kobe Bryant story was good for the NBA because it focused attention on professional basketball. In that spirit, Mr. Cuban said that to really concentrate the public’s attention on the game the Mavericks will employ snipers next season to randomly shoot unsuspecting fans as they sit in their seats at home games. No criteria for shooting fans have been established yet, but it is believed that season ticket holders will have nothing to worry about.
