At a typical football match we are likely to see players committing deliberate fouls, often behind the referee’s back. They might try to take a throw-in or a free kick from an incorrect but more advantageous positions in defiance of the clearly stated rules of the game. They sometimes challenge the rulings of the referee or linesmen in an offensive way which often deserves exemplary punishment or even sending off. No wonder spectators fight amongst themselves, damage stadiums, or take the law into their own hands by invading the pitch in the hope of affecting the outcome of the match.’
