For as long as there have been sports, there have been fans complaining about referees whose terrible calls rob their team of victory. The oldest - and most brutal - example of this can be found on a gladiator's epitaph.
I'm Spanish. I've been watching soccer—football—all my life, and I always wondered why the hell don't they use technology to solve one of the biggest problems of this game: Referees making bad calls. Like in today's USA-Slovenia game.
