Controversy and debate are a part of the game  Controversy will always be a part of the game; because laws must be interpreted by an individual, fouls will always be called on the basis of opinion, even if that is someone re-watching the incident on a monitor. If fans accepted mistakes as exactly that, they would cease to matter; the authority of the referee would be absolute and the game would move on without undue mention. GLT is unnecessary.  Sepp Blatter famously argued that "Fans love to debate any given incident in a game. It is part of the human nature of our sport"1. Supporters love to hate the referee; it provides them with a scapegoat for defeat. With GLT, the authority of referees would be irrevocably diminished. They would become merely cogs in a mechanic process of decision making. If we come to rely on cameras to govern the game, the passion is drained from it.  1 Ian Ladyman, Howard Webb calls for goalline technology as World Cup final referee returns to Barclays Premier League duty, MailOnline, 10th September 2010, (accessed 24/05/11)
