Instant video evidence for every top-flight and international soccer match should be introduced     

• because: introducing technology to assist referees in making judgment helps protect the players   
  • because: instant video playback deters defenders from committing any serious foul against the attacking players on the field with the hope of evading the referee's eyes   
• but: referees might become over-reliant on the technology   
• because: introducing instant video playback in assisting referees to make judgments makes the competition fairer   
  • because: instant video playback helps capture what is really happening on the football field, minimizing the referee's chance of making an incorrect judgment   
  • because: introducing instant video evidence helps prevent any diving, shirt-pulling, feigning injury and other negative plays from happening during the match   
    • but: the FIFA has already introduced retrospective punishment against any play-act and serious foul in the game to deter players from committing any unfair play   
      • but: it is rational that any player would rather dive to earn his side a penalty during the World Cup final in return for a one match ban afterwards   
        • but: the player could also be booked and sent off   
        • but: it would be rational but it would not be sporting   
    • because: there would be no incentive to dive or to pretend to be punched when someone in the stands can alert the referee immediately to the play-acting   
      • but: referees do not base decisions on the opinion of 'someone in the stands'   
• but: technology, instant video consulting would slow down and halt the flow of the game   
  • but: on the other hand, instant video evidence helps prevent time wasted for dealing with complains in contentious decisions, feigning injuries during the game   
  • but: other sports like rugby, cricket have also employed the same methods, while no big problem to the flow of the game is observed so far   
  • but: double-checking contentious decisions causes less than a minute   
• but: technology would undermine the authority of the referees and officials   
  • but: referees are not infallible, as serious mistakes in judgment, which altered the final result and ruined the game, were committed in the past   
    • because: for example, Maradona's "hand of god" goal in 1982 World Cup quarter final match, and Geoff Hurst's controversial second goal in 1966 World Cup final match   
  • but: it is the authority of the judgment per se, instead of that of the one who judge, that matters   
  • because: professional referees will become redundant if technology is introduced to give judgment for the game   
    • but: technology would assist referees, not replace them   
• but: introducing too many technologies to soccer match will render the game cold and computerized   
  • because: it is the liability to faulty, unpredictable or even unfair decision, i.e. human fallibility, that makes the game so exciting and attractive   
    • but: lack of fairness does not make the game more attractive
